Hi All,

My son has a 328i sedan that he bought used. When traveling over rough roads, there is a knocking sound coming from directly under the right rear passenger seat.
Any ideas what could be the problem? I had replaced the rear shocks, thinking they were the culprit, but to no avail.

I recommend replacement of the rear shock mounts with part# 33-52-1-092-362, this should stop the clunking. Realoem.com has them for 25 bucks each.
