I have a ml 320 and the door pockets have a horrendous rattle to them. It is so bad that I have had to stuff a folded towel in each of the front doors to prevent them from rattling. The rattles are mainly generated when I play music and it even does it when set at a quiet level.
I am mechanically inclined but have refrained from taking the door apart up until now because of the airbags.

Has anyone had a similar experience and what did you do to take care of the problem?
