Strut, noises

WARNING: This page does not describe the selected car, but rather 17 other vehicles, including the 2009 Audi S4, 2009 Audi A4, 2008 Audi S4, 2008 Audi RS 4, and 2008 Audi A4. However, it is still accessible from the selected car via links, so may be relevant.

Struts are frequently rejected and exchanged because of rumbling noises. Examinations on the test stand and vehicle have shown that there was not a complaint with approx. 70% of the rejected shock absorbers and the replacement was not justified.

With complaints that are interpreted as rumbling or knocking sounds, proceed as follows.

Determine on a road test with the customer - if possible on a dry stretch of road with irregularities - where, when and how these sounds change.

NOTE:

In the rarest cases, the strut is the cause of the noises.
