C320 Wagon Issues
Hi. I own a 2002 C320 Wagon, purchased used, still under factory warranty. Lately, I have been experiencing electrical problems. Dealer installed a new power seat module and said no more battery drain. Now, the Exit/Entry convenience (reset) does not cause the seat to move back all the way; the reverse mirror feature works occassionally; and when the passenger seat is moved forward or aft, the headrest goes up. I can also hear what sounds to be an electric motor running even when the key is out - this appears to be coming from the area where the sunroof controls are. Any suggestions as to what is wrong?
The other big concern is the vibrating/rumbling sounds from the rear hatchback or suspension. Sometimes the hatch sounds as though its vibrating. Other times the rear suspension is clunky and makes rumbling sounds.
So far the dealer has been pleasant. I picked up the car on Friday and noticed the above on the ride home - this is the wife's car. The dealer has the lower control arms on order for me. I really like this car and want to keep it for a while. Please let me know if any of you have experienced similar problems. Any feedback is appreciated
Thanks,
Alan

New DCM's fixed my reverse mirror issue along with the loosing of position in general. Otherwise, I would have to hear the noises you're talking about to be of any help.
Thanks for your feedback....The electric motor noise is coming from the area of the sunroof controls. I hear it even after 5 or 10 minutes, with key out and nothing else on.
The rear hatch/suspension sounds are twofold. First, occassional clunking & rattling. Second, vibrating (possibly rear hatch plastic).
The power accesory problem is becoming a nightmare. First a new battery. Second, a new power seat module. Now, the convenience features are out of whack. To make matters worse, the passenger seat headrest goes up when ever you move that seat foreward or rearward.
I've only had the car 4 months and its already spent 3 days in the repair shop. If this keeps up, I will unfortunately think the worst of MB and probably trade it for anything else. Too bad because I really do like this car, just find it a pain at the moment.
