1.1 Safety precautions when working on ve‐

hicles with a start/stop system

WARNING

All bolts and nuts must be fully tightened according to specifi‐

cations before the vehicle is driven on public roads.

WARNING

on vehicles with start/stop system.
♦ On vehicles with an active start/stop system the engine
may start automatically.
♦ When working on the vehicle, it is therefore important to

1.2 Safety precautions when working on

subframe
♦ No welding or straightening work can be done on the support
and guide elements of the wheel guide system.
♦ Always renew corroded nuts and bolts.
♦ Bonded rubber bushes can only be turned to a limited extent.
Therefore, tighten the bolted connections of components with
bonded rubber bushes only when the wheel bearing housing
has been raised (unladen state) ⇒ page 4 .

2.1 Leaks at shock absorbers

Shock absorbers are often replaced because of externally visible
leakage. Inspections on the test rig and in the vehicle have shown
that in the majority of cases this replacement is not justified.
Slight loss of fluid (“sweating”) at the piston rod seal is not a rea‐
son for replacing a shock absorber. A shock absorber with slight
fluid leakage can be accepted as "OK" under the following con‐
ditions:
♦ Fluid seepage (as shown in the shaded part of the illustration)
is visible, but the fluid is dull and possibly dried by dust.
♦ The fluid seepage extends only from the top shock absorber
seal (piston rod seal) down to the bottom spring plate
-arrow-.

2.2 Noises from shock absorbers

Shock absorbers are often replaced because of noises (rumbling,
etc.) experienced by the customer. Inspections on the test rig and
in the vehicle have shown that in approx. 70 % of these cases
there is no case for complaint. The replacement was not justified.
In the case of complaints regarding rumbling or knocking noises
please proceed as follows.
– Carry out a road test with the customer - if possible on a dry,
uneven road - to establish when, where and how the noises
occur. Protected by copyright. Copying for private or commercial purposes, in part or in whole, is not
permitted unless authorised by SEAT S.A. SEAT S.A does not guarantee or accept any liability with
respect to the correctness of information in this document. Copyright by SEAT S.A.

Note

These noises are only very rarely caused by the shock absorbers.

2 Rep. gr.00 - Technical data

GETtheMANUALS.org
León 2013 ➤ , León ST 2013 ➤
Running gear, axles, steering - Edition 02.2017

2.3 Checking shock absorbers when re‐

moved
Defective shock absorbers can be identified by loud rumbling
noises when driving, caused by wheel hopping, especially on bad
roads. Heavy fluid leakage is an additional visual indication.

Note

Shock absorbers are maintenance-free; shock absorber fluid can‐

not be topped up.

After removal, a shock absorber can be checked by hand as fol‐

lows:
– Compress shock absorber by hand.
• The piston rod should move smoothly over the entire stroke
with uniform resistance and without jolts.
– Release the piston rod.
• If the shock absorber has sufficient gas pressure the piston
rod will return by itself to its original position.

Note

♦ If this is not the case, the shock absorber does not necessarily
need to be renewed. Provided there has been no major loss
of fluid, it will still be as effective as a conventional shock ab‐
sorber.
♦ Even without gas pressure, the shock absorber will provide full
damping effect as long as there has been no major loss of fluid.
However, it may produce more noise.

2.4 Steering box

To achieve the desired results when performing repairs on the
steering box it is important to work with the greatest possible care
and cleanliness, and to use proper tools in good condition. Always
observe the basic safety rules when performing servicing proce‐
dures.

♦ Thoroughly clean all unions and the adjacent areas before
disconnecting.
♦ Ensure proper seating of dowel sleeves for centralising sus‐
pension bracket and steering box when installing.
♦ Place parts that have been removed on a clean base and cov‐
er them so that they do not get dirty. Use foil or paper. Use
only lint-free cloths.
♦ Only fit clean parts: remove the wrapping of the spares just
before use.
♦ Use only the grease and sealants with specified part numbers.
♦ If repairs cannot be carried out immediately, carefully cover or
seal open components.

2.5 Gaskets, seals

♦ Always renew oil seals and seals.
♦ Check contact surface on housing or shafts for burrs and dam‐
age after removing the seals, and repair as required.
♦ Completely remove all residue from liquid sealants from the
sealing surfaces, making sure that no residual sealant gets
into the steering box housing.

2.6 Bolts, nuts

♦ Loosen and tighten bolts or securing nuts for covers and hous‐
ings diagonally.
♦ Avoid canting particularly sensitive parts such as servo motor
with control unit. Loosen and tighten them diagonally in
stages.
♦ The specified torque values listed apply to unlubricated nuts,
bolts and screws.
♦ Always renew self-locking bolts and nuts.

2.7 Electrical components

No doubt you have been shocked when touching a metal object.
This is due to the electrostatic charge in the human body. This
charge can cause malfunctions if you touch the electric steering
box and steering column components.
– Before working on electrical components, touch an earthed
object, such as a water pipe or a lifting platform. Do not directly
touch connector contacts.

3.1 Checklist for evaluating running gear on

accident vehicles
Damage to running gear may go unnoticed during repairs to load-
bearing and suspension parts of accident vehicles. Under certain
circumstances, this undiscovered damage could lead to serious
consequential damage during later vehicle operation. Therefore,
the following parts of accident vehicles must be examined in the
manner and order described independent of wheel alignment
which may have to be performed. If no deviations from specifica‐
tions are measured during wheel alignment, there are no defor‐
mations of the

to the correctness of information in this document. Copyright by SEAT S.A.

♦ Visual examination for cracks and deformation.

♦ Examination for play in track rod joints and steering box
♦ Visual examination for defective boots and bellows
♦ Examination of electrical wiring and hydraulic lines and hoses
for chafing, cuts and kinks.
♦ Check hydraulic lines, threaded connections and steering box
for leaks.
♦ Check steering box and lines for secure seating
♦ Check for flawless function from lock to lock by moving the
steering from stop to stop. In the process, the steering wheel
must turn with a constant force without resistance.
Visual inspection and functional check of the running gear.
• Adhere to the sequence of the following inspection steps!
♦ Check all components shown in the assembly overviews for
deformation, cracks and other damage
♦ Renew damaged parts.
♦ Align the vehicle axles using a wheel alignment unit authorised
by SEAT.
Visual and functional check of wheels and tyres
♦ Check for true running and imbalance.
♦ Check tyres for cuts and impact damage in tread and on flanks.
⇒ page 312
♦ Check tyre inflation pressure; information on mandatory tyre
inflation pressure can be found on a sticker attached to B-pillar
on driver side or to inside of tank flap.
If rim of wheel and/or tyre is damaged, renew tyre. This also ap‐
plies if the circumstances of the accident and the damage to the
vehicle indicate possible damage which is not visible.
A further factor in the decision is the age of the tyre. Tyres should
not be older than 6 years.
If in doubt, the following always applies:
• Whenever a safety risk cannot be excluded, the tyre(s) must
be renewed.

hydraulic steering and other driver assist systems must be read
with the ⇒ Vehicle diagnostic tester for possibly stored fault mes‐
sages. If faults are saved in the event memories of the systems
mentioned above, repair them according to instructions in work‐
shop manuals in ELSA. Following repairs, read event memories
of the affected systems again to ensure that complete function
has been restored.

6.7 Checking outer constant velocity joint

The joint is to be dismantled to renew the grease if it is heavily
soiled, or to check the running surfaces of the balls for wear and
damage.
Removing
– Before dismantling, mark position of ball hub in relation to ball
cage and joint body with an electric scriber or oil stone.
– Swing ball hub and ball cage.
– Remove the balls one by one.

– Turn cage until the two rectangular windows -arrow- lie on joint
body.
– Take out cage with hub.

– Swing segment of hub into square cage window.

– Remove the hub from the cage.
The six balls for each joint belong to a tolerance group. Check
stub axle, hub, cage and balls for small indentations (pitting) and
traces of seizing. Excessive backlash in the joint will cause knock‐
ing or jolts under load change. In this case the joint must be
replaced. Smoothing and traces of wear of the balls are no reason
to change the joint.
Installing
Carry out installation in the reverse sequence, noting the follow‐
ing:
– Insert half of the recommended amount of grease (40 grams)
on the casing of the joint.
– Fit cage with hub into joint body.
– Fit opposite balls one after another. In doing so, take care to
re-establish the original position of the ball hub relative to the
cage and the joint body.
– Fit new retaining ring into hub.
– Distribute remaining grease in boot.

6.8 Checking inner constant velocity joint

Removing
The joint is to be dismantled when following work is done:
♦ Replacement of grease if very contaminated
♦ Check of running surfaces for wear
♦ Check of balls for wear
– Swing ball hub and ball cage.
– Push out joint body in direction of arrow.
– Press balls out of cage.

Note

Ball hub and joint body are paired. Do not interchange.

– Tip ball hub out of ball cage via ball track -arrows-.
– Check joint body, ball hub, ball cage and balls for small inden‐
tations (pitting) and traces of seizing.
Excessive backlash in the joint will cause knocking or jolts under
load change. In this case the joint must be replaced. Smoothing
and traces of wear on the balls are no reason to renew the joint.

– Also take note of chamfer on interior diameter of ball hub. It
must be visible after swivelling in.

– Swivel the hub into the joint body; at the same time the hub
must be swivelled out of the cage -arrows- far enough to allow
the balls to fit into the ball tracks.

– Press hard on the cage -arrow- insert turning the ball hub.

Removing
– Mark the position of the ball hub relative to the cage and the
housing before removing, use an electric pen or a softening
stone -arrow-.
– Swivel ball hub and ball cage and take out balls one after the
other.

– Turn cage until the two rectangular windows -arrow- lie on joint
body.

– Swivel one segment of the hub into one of the cage openings.
– Remove the hub from the cage.

Note

♦ The six balls for each joint belong to a tolerance group. Check
stub axle, hub, cage and balls for small indentations (pitting)
and traces of seizing.
♦ Too much circumferential backlash in the joint becomes no‐
ticeable during load change jolts; in such cases, the joint must
be renewed.
♦ Smoothing and traces of wear of the balls are no reason to
change the joint.

Installing
Carry out installation in the reverse sequence, noting the follow‐
ing:
– Press half of the total amount of grease from repair kit into the
joint body.
– Fit cage with hub into joint body.

Note

The cage must be placed in the correct position.

– Fit opposite balls one after another. In doing so, take care to
re-establish the original position of the ball hub relative to the
cage and the joint body.
– Fit new circlip in shaft.
– Distribute remaining grease in boot.

tations (pitting) and traces of seizing.

Note

Excessive backlash in the joint will cause knocking or jolts under

load change. In this case the joint must be replaced. Smoothing
and traces of wear on the balls are no reason to renew the joint.

large diameter of joint body.
– Also take note of chamfer on interior diameter of ball hub. It
must be visible after swivelling in.

– Swivel the hub into the joint body; at the same time the hub
must be swivelled out of the cage -arrows- far enough to allow
the balls to fit into the ball races.

Tyres which have been filled or sealed using tyre sealant must be
drained before removal.

Caution

♦ Avoid eye and skin contact with tyre sealant.

♦ It can cause injury, irritation to eyes and allergies.
♦ During this work, wear protective gloves and safety gog‐
gles.

Applies to alloy and steel wheels
When changing a wheel, wheel centring seat should be waxed
using wax spray to prevent corrosion between wheel centring seat
and rim ⇒ Electronic parts catalogue“ETKA” .
– Undo the wheel.
– Thoroughly clean wheel centring seat on wheel hub and the
centring ring of the wheel rim.
– Apply wax to centring area -arrow- with a brush.
Ensure that only centring ring -arrow- but not contact surface of
wheel rim has been waxed. Otherwise, the brakes will be soiled,
which would reduce the braking efficiency.

WARNING

Wheel bolts, contact surfaces of wheel hub and wheel rim and
wheel hub threads must not be waxed. Do not apply lubricants
or anti-corrosive products to the threads of the wheel bolts.

1.3.2 Wheel change, installation require‐

Warming cold tyres to minimum installation temperature

Note

This instruction also applies to ultra-high performance tyres

(height/width ratio smaller than/same as 45 % and speed symbol
greater than/same as V).

WARNING

The minimum installation temperature of a tyre should be be‐

tween 15°C and 30°C in the core of the tyre.

• To mount a tyre particularly on the top side and bead without

damaging it, the temperature of the inside of the tyre must be
at least 15 ℃.
• This temperature is described as core temperature.
• Rubber is a poor conductor of heat. Therefore, a cold tyre must
be left in an area with the correct temperature for a sufficiently
long period so the inner rubber layers can warm up to at least
15 °C.
• The surface temperature of the tyre during the warming up
phase is no indication of the internal temperature of the tyre.
• To enable cold tyres to absorb heat from the ambient air as
quickly as possible, they should not be stacked on top of one
another but instead stored individually in order to allow the
warm air to “circulate” around them effectively.
• The tyres may not be stored in front of a heater or be heated
with a hot air gun, since critical temperatures can be reached
very quickly on their surface.
• Except for warming with warm water or warm ambient air
(max. 50 °C), there is no process available for warming tyres

warm environment (above 0 ℃), a frost layer forms immedi‐
ately on the tyre surface. This frost layer shows that the tyre
intensively absorbs the ambient heat, whereby the humidity
condensates.
• Once the layer of frost has thawed, condensate water forms.
The condensation should be dried with a cloth so that the fur‐
ther warming process is not delayed due to a temperature drop
caused by evaporation.
Warming times:
♦ Tyres with a temperature of above 0 °C must be kept at least
at 19 ℃ for at least 2 hours.
♦ Tyres with a temperature of below 0 °C must be kept at least
at 19 °C for at least 2.5 hours.
Recommendation for heating:
♦ If possible, tyres should be stored in the workshop 1 day before

page 293

2.1 System description - tyre pressure mon‐

itoring system
General notes:
The tyre pressure monitor display is part of the software in the
ABS control unit - J104- . It detects the gradual reduction of the
tyre pressure of a wheel. Event memory entries for the tyre pres‐
sure monitor display are stored in the ABS control unit - J104- .
The tyre pressure monitor display compares the wheel speeds
and consequently the rolling circumferences of the individual
wheels with the help of the ABS speed sensors.
After the following work or modifications, the tyre pressure mon‐
itor display button - E492- must be pressed and held until a
confirmation is sounded.
♦ Change in tyre pressures
♦ Changing one or more wheels
♦ Swapping the wheels, e.g the front ones with the back ones
♦ Removing and fitting one or more wheels
A change in a wheel's rolling circumference will be indicated by
the tyre pressure monitor warning lamp - K220- lighting up in the
dash panel insert. A tyre's rolling circumference may change as
a result of:
♦ Insufficient tyre inflation pressure.
♦ Structural tyre damage. Protected by copyright. Copying for private or commercial purposes, in part or in whole, is not
permitted unless authorised by SEAT S.A. SEAT S.A does not guarantee or accept any liability with
♦ One-sided loading of vehicle respect to the correctness of information in this document. Copyright by SEAT S.A.

♦ Increased load on one axle, e.g. due to towing a trailer

♦ Use of snow chains.
♦ Temporary spare wheel installed
♦ Wheel renewal.
Fault in the anti-lock brake system
If there is an error message in the ABS through the control light
for ESP and ASR - K155- the control light of the tyre pressure
monitoring system will illuminate - K220- -1-. However, no fault
will be stored in the system for the tyre monitor display.
The warning lamp cannot be erased. In this case, please carry

⇒ Seat Servicenet; Documentation; Software and Updates; Soft‐
ware setting system for navigation.

Note

♦ Wheel alignment should not be checked before the vehicle has

completed 1,000 to 2,000 km because the coil springs must
settle.
♦ When making adjustments, adhere to the relevant specifica‐
tions as closely as possible.
♦ Whenever adjustments are made to the running gear, always
check whether any driver assist systems must be recalibrated
following the adjustments.

Vehicles pulling to one side; accident vehicles

This may be due to the rack in the steering box not being posi‐
tioned exactly in the centre when driving in a straight line.
Power steering assistance is thereby one sided slightly, rather
than central. This will cause the vehicle to drift.
Always check centre position of steering rack when performing
wheel alignment on a vehicle which “pulls to one side”.

Preparations required before calibration of driver assist systems

3.3.2 Test preparations, wheel alignment with

driver assist systems
The following steps are required if one or more driver assist sys‐
tems on the vehicle are to be calibrated via the “Quick-start”
procedure (i.e. without first checking and adjusting the wheel
alignment):
• Before driving the vehicle onto the alignment platform, make
sure there is sufficient space between the vehicle and the cal‐
ibration unit. The distance between the calibration unit and the
vehicle must be 120 cm ± 2.5 cm.
• If the available space is not adequate, move the vehicle back‐
wards on the alignment platform as required. This allows the
use of the respective floor area.
• Before calibrating, read out event memory and rectify faults as
necessary.
• Vehicle accurately aligned, suspension bounced and rocked
several times
• When checking wheel alignment, ensure that sliding plates
and turn tables are not touching end stop.
• Connect battery charger ⇒ Electrical system; Rep. gr. 27 ;
Battery; Disconnecting and connecting battery .
• Bring wheels into straight-ahead position.
• Connect up ⇒ Vehicle diagnostic tester to vehicle and run di‐
agnostic cable out through open window.
• Exterior lighting switched off.
• All vehicle doors closed.
• Press button to select required calibration on wheel alignment
computer.

3.4 Specified values for wheel alignment

If measured values are outside specified tolerances, this may be
because the vehicle is inclined.
Right-hand drive vehicles or e.g. vehicles with an automatic gear‐
box may lean to one side slightly.
This is due to the installation position of the assemblies and their
associated weight transfer and is normal.
– In such cases it is essential to measure dimension -a- at the
rear on both sides.
– Correct any differences as required.
The front axle may be balanced by attaching balance weights on‐
to the suspension turret on the corresponding side, in the engine
compartment. Protected by copyright. Copying for private or commercial purposes, in part or in whole, is not

3.5 Wheel alignment procedure

Overview - wheel alignment procedure

Note

The vehicle must always be in unladen condition when measuring

wheel alignment ⇒ page 4 .

Operations should be carried out in the order shown!

1- Drive vehicle onto wheel alignment unit and ensure that
suspension is not under stress, if necessary by moving ve‐
hicle backwards and forwards several times.
2- Before the initial measuring and the adaption work, the
steering wheel must be “centred” by moving it back and forth
equally in order to move the steering back to the centre po‐
sition again.
3- Carry out wheel rim runout compensation ⇒ page 310 .
4- Check full steering lock ⇒ page 311 .
5- Check camber at front wheels and centralise if necessary
⇒ page 305 .
6- Check camber at rear wheels and adjust if necessary
⇒ page 307 .
7- Check toe setting at rear wheels and adjust if necessary
⇒ page 308 .
8- Check toe at front wheels and adjust if necessary
⇒ page 309 .

Note

♦ If adjustments have been made to the suspension after a

wheel alignment check on vehicles with ESP or ABS, the
steering angle sender - G85- must be calibrated using the
⇒ Vehicle diagnostic tester.
♦ If any changes are made to the rear wheel alignment settings,
the following driver assist systems must be recalibrated:
♦ Lane departure warning (Audi lane assist)

3.11 Wheel runout compensation

If runout compensation is not performed, it is not possible to adjust
toe-in correctly!
The existing lateral run-out of the wheel rims must be compen‐
sated accordingly. Otherwise false results will be obtained.
A certain amount of axial runout at the wheel rims is permissible,
but this may already exceed the specified toe-in tolerance. In such
cases it is not possible to set the toe-in correctly without first com‐
pensating for the wheel runout.
Follow the instructions from the manufacturer of the axle meas‐
urement equipment

3.12 Vehicle data label

Explanation regarding “PR numbers” on vehicle data sticker
Various types of running gear are installed depending on engine
and equipment level. These are identified by the PR numbers.
The PR numbers are critical in determining the wheel alignment
specifications.
The running gear version fitted in the vehicle is indicated on the
vehicle data sticker by the PR number for the front axle.
The vehicle data sticker can be found in the spare wheel well and
in the service booklet.

3.13 Checking full wheel lock

The wheel alignment computer is used to determine the full steer‐
ing lock.
– When the values for the maximum wheel lock lie outside the
tolerances, then check following:
♦ Are steering or suspension components damaged or de‐
formed?
♦ Are track rods visually OK.?
♦ Is the symmetry of the track rods OK.?
Damaged components must be renewed.
– If the steering wheel is crooked, check the following:
♦ Check steering components for damage and deformation. If
necessary, renew damaged components.
♦ Check suspension components for damage and deformation.
If necessary, renew damaged components.
♦ Also check the symmetry of the track rods.
– Measure dimension -a- of “shorter” track rod. Shorten the “lon‐
ger” track rod end to the same dimension. To do so, screw
track rod ball joint -1- further onto track rod -2-.
Dimension -a- must be the same on left side and right side track
rod ball joint.
Maximum permissible difference between left and right < 2.5 mm.
– On returning the steering to the centre position, allow the
steering wheel to “settle” with uniform movements.

4.1 Causes of imbalance when driving

The causes for the unevenness during the journey are varied: ride
disturbance may also be caused by tyre wear. Tyre wear caused
by driving is not always evenly spread across the entire running
surface of the tyre. This causes slight imbalances which affect the
smooth running of a wheel which was previously exactly bal‐
anced.
These small imbalanced actions cannot be perceived on the
steering wheel, but they are there. They increase tyre wear and
reduce the operating life of the tyres.
Recommendation
To ensure
• optimum safety
• smoothest possible running and
• equal wear
throughout a tyres service life, we recommend having the wheels
and tyres balanced at least twice during the tyres service life.

4.2 Conducting a road test before balancing

wheels
If a complaint is received for “imbalance while driving” the vehicle
should be taken for a test drive before starting the balancing.
♦ With this, the reason for uneven running is determined.
♦ You will be able to determine the speed range in which rough

Note

♦ To clamp the wheel in place, use centring system for wheel

balancing machines - VAS 5271- , for example.
♦ This ensures that the wheel is 100% centred and that the
wheel will be clamped without damage!
♦ The wheel cannot be centralised 100% with conical clamping
elements on the wheel balancing machine.
♦ A centring arrow of 0.1 mm corresponds to an imbalance of
10 g.

Procedure for balancing the wheel rim / tyre

– Allow the wheel (together with tyre) to rotate on the wheel bal‐
ancing machine.
– Check that the indicator lines on the sidewall of the tyre near
the rim flange run evenly.
– Check that the body of the tyre runs evenly while the wheel
and tyre are rotating.

Note

If one-sided wear, flat spots from braking or severe erosion is ap‐

parent, balancing will not be able to achieve smooth running. In
this case, the tyre must be renewed.

– Check true running of the wheel/tyre. If not all the wheel turns
in a concentric manner, and if no flattening has been detected,
there may be radial or axial run-out.
– Check the wheel for radial or lateral runout ⇒ page 318 .
– If the radial and axial run-out do not exceed the permitted tol‐
erance levels, balance the wheel and the tyre.

tion control system - VAS 6230 A- ⇒ page 317 .

– Bolt the wheel to the vehicle.

– First, hand-tighten the lowest wheel bolt to about 30Nm.
– Then, tighten the remaining wheel bolts diagonally to about
30Nm. This process centres the wheel on the hub.
– Lower vehicle onto its wheels.
– Now use the torque wrench to firmly tighten the wheel bolts
diagonally to the prescribed torque.

If any imbalance is detected during the test drive, this may be due
to tolerances in the centre of the wheel.
In unfavourable circumstances, the tolerances of the wheel com‐
ponents and the wheel hubs may be added together, this can also
cause imbalance while driving. This can be alleviated using a fin‐
ish balancer. ⇒ page 317

4.3.3 Balancing wheel, balancing wheel with

finish balancer

Note

♦ Before working with a finish balancer , the mechanic needs to

have been instructed by the manufacturer of the balancer.
♦ To balance the wheels, set the wheels of the driven axle on
the sensor platforms. On front-wheel drive models, front
wheels must be set. On four-wheel drive models, all 4 wheels
must be set.

If a residual imbalance of over 20 grammes is detected during the

balancing procedure, the wheel should be turned on the wheel
hub.
– Mark the point at which the imbalance is indicated.
– Then, unbolt the wheel and rotate its position on the hub so
that the marking points downwards.

Note

The wheel hub should not rotate during this process.

– First, hand-tighten the lowest wheel bolt to about 30Nm.

– Then, tighten the remaining wheel bolts diagonally to about
30Nm. This process centres the correctly wheel on the hub.
– Check whether the imbalance is less than 20 grams using the
finish balancer.

Note

The counterweight should only be modified if the imbalance is

under 20 grammes.

– Loosen the wheel bolts again if necessary.

– Rotate wheel again by 1 or 2 wheel bolt holes permitted

4.4 Vibration control system

The vibration control system - VAS 6230A- has a range of addi‐
tional features over and above regular static wheel balancing.
A special feature of this system is the testing of the radial force of
the wheel and tyre while rolling.
For this purpose, a roller presses against the wheel with a force
of approx. 635 kg. In this way, the vertical force applied by the
tyre onto the road while driving is simulated.
The contact forces on the tyre vary due to variations in the stiff‐
ness of the tyre and the degree of radial and lateral run-out on the
wheel/tyre.
The -VAS 6230A- detects and memorises the position of maxi‐

4.5.1 Checking radial and lateral runout of

wheels and tyres, tolerances
Radial and lateral runout occur when the wheel and tyre do not
run absolutely true.
For technical reasons, 100% true running is not possible.
For this reason, the manufacturer specifies certain tolerance lev‐
els for these elements.
Aligning the tyre in an unfavourable position on the wheel can
cause the maximum allowed tolerance for wheel with tyre to be
exceeded.
The table shows the maximum permissible tolerances for a wheel
with mounted tyre.

4.7 Matching wheels and tyres
General information
When radial or lateral runout of the wheel and tyre coincide, the
imbalance of the wheel is amplified by the tyre.
For technical reasons, 100% true running is not possible
⇒ page 317 .
Before match mounting the used wheels which are fitted on the
vehicle, run the tyres warm. By doing this you will eliminate any
existing flattening ⇒ page 320 .
Match balancing process
– Let air out of tyre.
– Press tyre beads off wheel rim flanges.
– Apply tyre assembly paste all round the tyre beads.
– Rotate tyre by 180° in relation to disc wheel.
– Pump up tyre to approx. 4 bar.
– Attach the wheel (together with tyre) to the wheel balancing
machine.
– Check wheel for true running and for radial and lateral runout .

Note

♦ If the theoretical values for radial and axial run-out are not ex‐
ceeded, the wheel can be balanced to 0 grammes. The nom‐
inal values are specified in ⇒ page 319 .
♦ If the radial and lateral runout is not within the specifications,
the tyre must be rotated again.

– Let air out and press tyre beads off the wheel rim flanges.
– Rotate tyre by 90° in relation to disc wheel (quarter of a turn).
– Pump up tyre again to 4 bar and check true running.

Note

♦ If the theoretical values for radial and axial run-out are not ex‐
ceeded, the wheel can be balanced to 0 grammes.
♦ If the theoretical values for radial and /or axial run-out are still
exceeded, proceed as follows.

– Press tyre off wheel rim flange again as described above.

– Turn the tyre by 180° (1/2 turn) with respect to the rim.

If the measured values for radial and lateral run-out of the wheel
are within the specified values, the tyre has an impermissibly high
radial or lateral run-out. In this case, the tyre must be renewed.

Note

As assembly paste has been used between the tyres and the
contour of the wheel rim during the assembly of the wheel, ac‐
celeration and sharp braking should be avoided for the first 100
to 200 km. Otherwise the tyre may spin on the wheel rim and all
the above work will have been in vain.

4.8 Determining flat spots on tyres

What is flattening?
Flattening is also known as flattening out .
Flattening out may cause imbalance when driving, as does a
poorly balanced wheel. It is essential to recognise flattening of the
tyre band as such.
Flattening cannot be balanced. It may reappear for different rea‐
sons at any moment. Complex tools are needed to remedy this,
assuming a flat spot due to sudden braking.

Note

Flattening as a result of braking can not be repaired. Tyres dam‐

aged in this way should be replaced.

320 Rep. gr.44 - Wheels, tyres, vehicle geometry

GETtheMANUALS.org
León 2013 ➤ , León ST 2013 ➤
Running gear, axles, steering - Edition 02.2017

Reasons for flattening

♦ The vehicle is left standing for several weeks without being
used.
♦ The tyre pressure is too low.
♦ After being painted, the vehicle was left in the drying kiln of the
painting workshop.
♦ The vehicle was parked while the tyres were hot in a cold ga‐
rage or similar place for a long period of time . In this case,
flattening may even occur overnight.
Solutions in the event of flattening
♦ The flattening out of tyres can not be corrected using workshop
tools.
♦ This flattening out can only be removed by driving on the tyre
until it warms up.
♦ The method described below is not recommended in cold and
wintry weather.
Requirements/conditions
– If necessary, check tyre pressure and correct.
– If possible, drive the vehicle onto a motorway.
– Traffic and road conditions permitting, drive a 20- to 30-kilo‐
metre stretch at a speed of 120 to 150km/h.

WARNING

♦ Do not endanger yourself or other road users during this

road test.
♦ Observe the highway code and speed limitations in force
when performing the road test.

– Jack up the vehicle immediately after the trip.

– Unbolt wheels from vehicle.
– Balancing wheels on stationary wheel balancer ⇒ page 313 .

4.9 Lateral deviation: verification

bulging sides, flattening and/or damage to the tread.
– Ask the client whether there have been any flat tyres which
were repaired in a workshop; replace the tyre if necessary;
– Check tyres for uniform wear and tread depth.
– Check all the tyres are the same type, make and have the
same tread pattern.
– If the tyres do not have a stipulated rotation direction, check
whether the tyre DOT markings are on the outside. If not, the
rims / tyres have been previously interchanged;
– The road surface should be straight and flat, without lateral
cambers or dips.

– Carry out the test drive in the company of client, following the
above-mentioned points(the client should drive in order to
demonstrate the complaint).

Note

The test can not be carried out in the event of strong side winds

If the complaint is justified, the wheel rims / tyres should be inter‐

changed as described below:
Before commencing, the following instructions should be ob‐
served. Otherwise, the work may be carried out in vain

Note

♦ Mark the wheels / tyres before interchanging for the first time,
for example with LF, RF, LR and RR.
♦ After interchanging the wheels or turning the tyre on the wheel
rim, the performance of the vehicle should be checked on a
test drive. Make a note of how and what has changed.
♦ Assess the intensity of or possible modification to the lateral
pull.
♦ It is also important that the test drives are made by the same
person and along the same roads. It is best to drive along the
road in both directions.
♦ Replacing a tyre with a new tyre does not necessarily guar‐
antee that the pulling to one side will be eliminated. A selective
interchanging of the tyres should first be carried out as descri‐
bed below.
♦ Where there is considerable difference in the tread depth of
the tyres on the front axle in comparison with the tyres on the
rear axle, the tyres with the better condition tread should al‐
ways be fitted on the front axle.

5.1.1 Calibrating Adaptive Cruise Control

(ACC)
Before calibrating the adaptive cruise control (ACC), it must be
ensured that the sensor, the retainers and the fixing elements do
not have any damage and are fastened properly. Where neces‐
sary, damaged components are to be repaired or renewed.
Before adjustment of the Adaptive Cruise Control (ACC) system,
the event memory must be read out and faults, if any, rectified.
The “measured misalignment-angle value” of the ACC control unit
will indicate whether or not the sensor is out of adjustment.
Calibration of the adaptive cruise control (ACC) must only be car‐
ried out using a wheel alignment unit and adjustment equipment
approved by SEAT!
Correct adjustment is an essential prerequisite for perfect func‐
tioning of the Adaptive Cruise Control (ACC) system.
