Remedial
Action:
Before doing any other work, the symptom must be simulated using a test procedure.
(Opening the door windows can be helpful when evaluating noises).
1 Conditions for the first test procedure:
* Activate the Start/Stop function and
* deactivate all sources of noise in the vehicle (Entertainment, ventilation, etc.).
* A multi-story parking garage can be useful for acoustic reverberation.
* On a straight stretch
* from speeds less than 10mph (20 km/h)
* brake the vehicle to a standstill.
* The best way of finding the clicking noise is by driving slowly and then stopping the vehicle.
