My 02 C4S has a rattle that is driving me crazy (like so many others). I know it's difficult to isolate an interior rattle, but if I didn't know better I'd say it is a speedometer cable noise, which seems to be coming from the passenger rear. Checked the seatbelt tensioner, rear speaker, and since the sunroof is being repaired was able to take that off the list of possibilities. Only happens when going over rough road, whether accelerating or decelerating. Any new (or old) ideas? I've checked out the forum re muffler, cat, windows, mirror, and as far as I can tell these aren't the culprits. Any help really appreciated -- tired of turning the radio up to drown out the noise.

drateam,

I am not sure it would be the speedo cable if it only happens over bumpy roads. One common "noise" issue is the baffles in the mufflers break loose inside and create various rattle like sounds.

I haven't encounteres this in my car and am not sure how many miles you have on your car. DO a search of muffler noise and will probably find some threads tha tcover this issue in more detail.

Good Luck!! demosan

demosan (and anyone else with a similar rattle),

I've finally figured out the rattle problem. First, I would have sworn that it was coming from the passenger side rear, but it's actually the driver side rear seat belt retracting mechanism -- the device that you can't get to without removing the rear interior panel. I haven't done this yet, but no matter what the problem is (not securely attached, broken mechanism, etc.) it's out of here. For me, the whole rear "seat" set is totally unusable, so it's all going. Less weight, less hassle and one less rattle. Now, on to the driver's side seat belt adjusting mechanism, which squeaks and rattles too. Hope this helps anyone with a similar problem.

drateam,

Glad to hear you found the solution to those d*** rattles. I never have had anyone is the back seat of my C4S, so that's one I don't suffer from.

THanks for sending this closure thread.
