I've been an owner for all of 10 days--just bought a 2004 M3 with 38,600 miles on it. The unfortunate thing is that I think I already have a problem with it. When I got into the car last Thursday night (travel for work, so hadn't driven it since the previous Sunday) I noticed a rythmic rubbing/grinding in the front right wheel well, even when rolling in the driveway. It doesn't change when I turn in either direction. There's no vibration in the steering wheel, and the sound is pretty noticeable up until 30-40 mph, when the noise of the engine and other ambient noise drown it out. I have taken it up to 70-80 mph on the highway and there is no vibration with it either. Anyways, I took it back to the dealership where I got the car (Honda dealership, but I at least had a chance of getting the repairs paid for by them) and after talking with them several times over the phone this week, they said they've test driven it a few times and cannot hear the noise. I thought that the noise might have been less pronounced as I was driving to drop it off at the dealership, but I thought it would still be audible to them. I will obviously check to see if I can hear it on Friday when I pick it up, but is there a good chance that there was a minor amount of rust buildup on some parts in/near the wheel assembly over those 4-5 days (drove in rain that Sunday, and left in the garage until Thursday night) that after some driving, friction would take the rust off? Thanks for any replies.
