Initial publication
Customer states:
• There are cracking or creaking noises when steering that come from the front end near the steering column,
intermediate steering shaft, steering rack, and/or the steering wheel.
Technical Background
Noises from dynamic steering actuator due to tolerances.
Production Solution
Under development.
Service
To narrow down the source of the noise, proceed as follows:
• Remove the fuse for the dynamic steering, J792 (address word 001B). This disables the actuator.
• If the noises now no longer occur when steering, the dynamic steering actuator is the cause of the noises that
were heard previously.
