Ignition Lock: Service and Repair

Removing and installing ignition steering lock

Removal
1. Disconnect battery.

2. Remove steering wheel. Observe safety precautions for airbag vehicles.

3. Remove shrouding of airbag contact unit or steering column switch.




4. Remove airbag contact unit, disconnecting the plug and undoing the fastening screws.




5. Remove steering column switch. Take off switch cover and steering lock shroud.

6. On vehicles with Keylock, remove the bowden cable for the steering lock. Before removing the cable, turn ignition key to "II" position (ignition on). Then remove bowden cable from ignition steering lock (arrow) (screw connection).

Note



The ignition steering lock must remain in the "II" position. If it is in any other position, the ignition steering lock and the Keylock bowden cable are damaged.

7. Disconnect instrument cluster plug (to improve accessibility), connector of ignition switch and buzzer contact switch.




8. Drill Out shear bolts of steering lock housing. Take out steering lock housing.


Installation

1. Insert ignition steering lock with lock pin disengaged into vehicle - steering lock position "II".

2. Align steering lock housing, pin of steering lock must engage easily. Tighten shear bolts, taking care not to shear the bolts.




3. For Keylock vehicles, screw in bowden cable at ignition steering lock position 'ii" (selector lever must not be in position "P"). Then move selector lever to position "P" and turn ignition steering lock to position "0".

Note



If the ignition steering lock cannot be turned to the "0" position, the cable adjustment must be corrected as follows:

- Set selector lever to position "P".
- Turn ignition steering lock to position "II" and then turn back to position "0" again.
- Adjust bowden cable, turning the bowden cable at the slide housing (No.1) until distance (A) between the notch at the locking slide (No.2) and the mark edge at the gate (No.3) is 6 mm.
- When turning the cable, use a second wrench to lock at the square of the slide housing (No.4).

4. Fit connectors of ignition steering lock, instrument cluster and buzzer contact.

5. Check ignition steering lock operation (operation of lock pin) and Keylock operation.

6. Fit steering column switch.

7. Align steering column stalk as follows:

Vehicles without airbag
- Fit steering wheel provisionally.
- Adjust clearance between steering column switch and steering wheel. Specification = 2 - 4 mm.
- Tighten steering column switch screw.

Vehicles with airbag



- Using a depth gauge, set dimension 45 ± 0.5 mm.
- Tighten steering column switch.
- Measure between beginning of steering shaft and center of steering column switch.

8. Fit airbag contact unit. Use two new screws.

Note



Before fitting the contact unit, set the front wheels to the straight-ahead position and set the contact unit to the center position (approx. 4 1/2 turns from left-hand or right-hand full lock). The precise center position is indicated by the two arrows.

A new contact unit is locked in the center position. The lock is only removed after fitting the contact unit.

9. Shear off the shear bolts after all visual and functional checks of the relevant parts have been carried out.

10. Fit covers and trim panels.

11. Fit steering wheel.
