Checking and adjusting the hydraulic steering limiter
1 - Limiting valve (arrow); 2 - Hex bolt; 3 - Locking insert; 4 - Lid; 5 - Steering wheel
1. Jack up the front of the car and place it on supports.
2. Unscrew the hex bolt (2) and remove it together with the locking insert (3).
3. Screw the limiter valve (arrow) into the steering gear housing until it stops, then release it by 2-2.5 turns.
Note: There is only one limiter valve (1) operating in both directions of steering wheel rotation. Accordingly, the selected valve setting will also operate in both directions of rotation.
Caution! Do not release the limiter valve more than 2.5 turns when the engine is running.
4. Remove the airbag module from the steering wheel (see Chapter On-board electrical equipment).
5. With the engine running at 800 rpm, turn the steering wheel all the way to the left.
6. Place an end wrench on the steering shaft bolt/nut, pull it until it stops against the steering stop with a force of approximately 25 Nm and fix it in this position.
7. Slowly screw the pressure reducing valve into the steering gear housing until a resistance of 20 Nm is achieved, ensuring the required parameters are set.
8. Screw in the locking insert (3) and the hex bolt (2).
Note: If the insert cannot be seated on the hex head of the pressure reducing valve after adjusting the latter, correct the position of the valve by tightening it clockwise to the required angle.
9. Reinstall the driver's airbag module.
