Op nbr 42161
Measuring tool ZF 1PO1 137 833 or E1665 Measuring tool
Sliding depth caliper
Sliding caliper
Socket 24 mm (0.9 in), spark plug type
Torque wrench 0–100 Nm (0–10 kpm) (0–73.8 lbf ft)
1. Turn off the main electric power with the battery disconnect switch.
2. Remove underbody skid plate 3 under the transmission, see [Invalid linktarget] .
3. Remove the cover for the inductive sensor.
Disconnect the cable terminals from the inductive sensor.
Remove the inductive sensor (24 mm (0.94 in) socket).
NOTE!
Make sure that the adjusting washers come out with the sensor.

4. Place the lock ring on the measuring tool, approx. 1 cm (0.39 in) from the end.
Push the tool into the sensor location until it stops against the toothed disc.

Measurement "a"
6. Measure and note measurement "b" from the end of the inductive sensor to its shoulder.
Subtract the measuring tool’s measurement from the inductive sensor measurement.
The difference should be 0.6–0.8 mm (0.024–0.032 in), which is the same as the correct thickness of the adjusting
washer/washers.
Adjusting washers are available in thickness from 0.6–3.0 mm (0.024–0.118 in), with a difference in thickness of
0.2 mm.

7. Fit the inductive sensor with the correct thickness of the adjusting washer/washers.
Max. tightening torque is 50 Nm (5 kpm) (36.9 lbf ft).
Connect the cables and fit the cover, see [Invalid linktarget].
