GENERAL REPAIR NOTES

Safety precautions

CAUTION: Fuel system is under high pressure! Before opening high pressure
components of the fuel injection system, pressure must be relieved to
residual pressure --> Procedure that must be performed before opening
the high-pressure fuel injection system - Pay close attention!. Then wrap a
clean rag around the connection and relieve residual pressure by carefully
loosening the connection.

To reduce the risk of personal injury and/or damage to the fuel injection and ignition system, always
observe the following:

 The ignition must be switched off before connecting or disconnecting injection and ignition system
wiring or tester cables.
 It is possible that the control module will recognize a malfunction and store a DTC during some tests.
Therefore, when all tests and repairs are completed, the DTC memory must be checked and, if necessary,
erased. After DTC memory is erased, a readiness code must be generated for engine control module using
operating mode "Guided Fault Finding".
 Clean engine only with ignition switched off.

Rules of cleanliness for performing work on fuel injection system

Even minor contaminations can lead to malfunctions in the fuel injection system. Therefore when working on
the fuel supply/injection system, pay careful attention to the following rules of cleanliness:

 Before loosening, connections and surrounding areas must be cleaned thoroughly with engine or brake
cleaner, and then cleaned area must be dried completely.
 Plug open lines and connections immediately with appropriate protective caps.
 Place parts that have been removed on a clean surface and cover them. Do not use fluffy cloths!
 Only install clean components: Only unpack replacement parts immediately prior to installation. Do not
use parts that have been stored unpackaged (e.g. in tool boxes etc.).

 When system is open: Do not work with compressed air. Do not move vehicle unless absolutely
necessary.
 Protect disconnected electrical connectors from dirt and moisture and only connect if dry.

Procedure that must be performed before opening the high-pressure fuel injection system - Pay close attention!

The fuel injection system is separated into a high-pressure section (max. approx. 110 bar) and a low-pressure
section (approx. 6 bar).

Before opening the high-pressure section - e.g. removing the high-pressure pump, fuel rail, fuel injectors, the
motor for intake manifold runner control valve or any other component or fuel line that is located in the high-
pressure section of the fuel injection system - the fuel pressure in the high-pressure section must be relieved to a
residual pressure of approx. 8 bar. The procedure for this is as follows.

 Start engine and run at idle speed.

CAUTION:  Worn sodium-filled exhaust valves must not be scrapped without first
being properly treated.
 Using a metal saw, the valves must be cut into two pieces between
the shaft center and valve head. While doing this, do not come into
contact with water. At the very most, throw 10 of the prepared valves
into a bucket filled with water. Then, move quickly away, because a
sudden chemical reaction will occur during which the sodium is
burnt away.

Filling

 Ignition switched off.

NOTE:  The cooling system is filled all year round with a mixture of frost and
corrosion protection additives and water.
 Use only coolant additive Plus G 012 A8F A1 (short: G12+ ) "according to
TL VW 774 F". Other coolant additives may above all reduce the corrosion
protection effect significantly. The damage resulting from this may lead to
loss of coolant and consequently to severe engine damage.
 Coolant additive G12+ can be combined with additives G11 and G12.

 G12+ and coolant additives with the designation "according to TL VW 774


F" reduce frost and corrosion damage as well as lime deposits. They also
raise the boiling point. For this reason the system must be filled all year
round with frost and corrosion protection additives.
 Because of its high boiling point, the coolant improves engine reliability
under heavy loads, particularly in countries with tropical climates.
 Protection against frost must be assured to about -25 ° C (in arctic climatic
countries to about -35 ° C).
 The coolant concentration must not be reduced by adding water even in
warmer seasons and in warmer countries. The coolant additive portion
must be at least 40%.
 If for climatic reasons greater frost protection is required, the amount of
G12+ can be increased, but only up to 60% (frost protection to about -40 °
C), otherwise frost protection and cooling effectiveness will be reduced.
 Only clean drinking water may be used for mixing coolant.
 If the radiator, heater core, cylinder head and cylinder head gasket or
cylinder block is replaced, completely replace the engine coolant.
 Dirty coolant must not be re-used.
 For coolant G12+ , use refractometer T10007 to test frost protection in
cooling system.
 Secure all hose connections using hose clamps appropriate for the model
type .
 Replace seal.
