Removing
• Correct any faults stored in the Diagnostic Trouble Code (DTC) memory before replacing the steering gear. Refer to the vehicle diagnostic tester.
- Connect the vehicle diagnostic tester and start the "Guided Fault Finding".
Follow the instructions on the screen.
- Turn the steering wheel to the straight ahead position and remove the ignition key so that the steering wheel lock engages.
Vehicle with "Keyless Access" Keyless Locking and Starting System
- Turn the ignition off and open the driver door so the steering wheel lock locks.
Continuation for All
- Disconnect the battery.
- Remove the foot well trim retainers - arrows - and trim - 1 -.
- Remove the bolt - 1 - and remove the universal joint - 2 - from the steering gear.
- Remove the front wheels.
- Loosen the tie rod end to wheel bearing housing nut, but do not remove it yet.
To protect the threads, leave the nut on the stud a few turns.
- Press out the tie rod end from the wheel bearing housing using the ball joint puller (3287A) and now remove the nut.
- Remove the lower noise insulation.
- Remove the coupling rods from the stabilizer bar.
- Remove the ball joint nuts - arrows -.
- Remove the pendulum support bolts - 13 -.
- Remove the exhaust system suspended mount bolts - arrows - from the subframe.
With Front Wheel Drive (FWD)
- Remove the heat shield bolts - arrows -.
- Remove the heat shield from the subframe.
Continuation for All
- Remove the steering gear bolts - 5 and 6 -.
- Remove the stabilizer bar clamp bolts - 7 and 8 -.
- Secure the subframe. Refer to => [ Subframe, Securing ] Subframe, Securing.
- Disconnect the connector for the oil level thermal sensor, if equipped.
- Place the engine-/gearbox jack (V.A.G 1383 A) under the subframe.
- Place a block of wood - 1 - between the engine-/gearbox jack (V.A.G 1383 A) and the subframe.
- Remove the subframe bolts - 9 and 10 - and slightly lower the subframe. Pay attention the electrical wiring while doing this.
- Remove the heat shield - 1 - above the exhaust system.
- Remove the bolts - arrows -.
- Remove the wire guide - arrow -from the subframe.
- Unclip all other mounting points on the steering gear.
- Disconnect the connectors - 1 and 2 - from the steering gear.
- Carefully lower the subframe using the engine-/gearbox jack (V.A.G 1383 A).
- Now, lift the stabilizer bar - 1 - toward the front, over the subframe - 2 - and down, while turning the stabilizer bar slightly.
- Lift down the steering gear from the subframe.
- Set down the steering gear as shown in the illustration.
This prevents damage to the control module - 1 -.
Installing
Installation is the reverse of removal, with special attention to the following:
- Make sure the white pressure membrane - arrow - is clean and not damaged.
- If necessary, carefully clean the pressure membrane.
• If the pressure membrane is damaged, then the steering gear must be replaced.
- Connect the connectors - 1 and 2 - so that they audibly click into place.
The threaded sleeve must seat in the subframe hole.
• Coat the seal on the steering gear with lubricant, for example, soft soap, before installing the steering gear.
• After placing the universal joint onto the steering gear, make sure that seal on the steering gear makes contact on the plate without kinks and opening to the foot well is correctly sealed. Ingress of water and/or noises may be the result.
• Make sure sealing surfaces are clean.
Before fastening the bolts for the subframe, position the steering gear on the subframe and fasten the bolts for the steering gear and stabilizer bar clamps.
- Install the lower noise insulation.
- Bolt the universal joint to the steering gear.
- Connect the battery.
- Perform the steering angle sensor basic setting using the vehicle diagnostic tester.
It is necessary to adapt the electromechanical power steering using the vehicle diagnostic tester if a new steering gear was installed.
- Adapt the electromechanical power steering using the vehicle diagnostic tester.

Adapting electro-mechanical steering
Follow the instructions on the screen.
• If the vehicle is equipped with park assist 2, then the power steering control module (J500) must be coded again. Refer to the vehicle diagnostic tester.
After installation, the position of the steering wheel must be checked with a road test.
If the steering wheel is at an angle or a new steering gear was installed, the vehicle must be aligned.
- Perform a vehicle alignment. Refer to => [ Vehicle Alignment ] Vehicle Alignment.
