Customer statement / workshop findings
Creaking noise from the front suspension when manoeuvring

Technical background
Verify that the customer complaint matches the sound file within the Bentley Hub – Reference TPI Transaction number 2048616/TIP: When listening to the sound file the noise can be heard from between 0 and 3 seconds
The noise present in the sound file is caused by defective Lower suspension lever - Rear - Hydraulic mounts. In order to reproduce the noise this
bush must be twisted, therefore the noise can appear in the following circumstances
•

When performing parking manoeuvers with the brake applied

•

When steering from lock to lock with the vehicle in motion and the brake applied

•

When the vehicle is moved with steering input over uneven surfaces (for e.g. a ramp or speed bump)

If the customer complaint occurs in any of the above circumstances and the noise can be clearly assigned to the noise within the sound file –
Refer to the instructions within the Measure section of this TPI

VERY IMPORTANT NOTE FOR HYBRID VEHICLES:
•

Hybrid vehicles use a High voltage system and MUST only be worked on by suitably qualified personnel.

•

Please ensure all guidelines within the repair manual are strictly followed before and whilst conducting any work on
vehicles with a High voltage system
