Just picked up a 99 M3 last weekend and love it.
So far, its a flawless car, visually and mechanically, but there's one thing that's driving me nuts:
While driving, I occasionally hear a very short, high pitched chirp or squeeling sound that seems to be coming from the rear right side of the car. It sounds a lot like the squeel you hear from the factory issue brake pads, but it never happens while I'm on the brakes. It seems to happen intermittantly at any speed, in any gear. At first, I thought it was one of the rear brakes, but now I'm not so sure. I've even tried coasting on a smooth, level road and pulled up the E-brake slightly to listen for the chirp. Didn't happen.
Anyone have any ideas what this could be??
I've had the same problem since I got my car, its been 2 years already, first time I heard it I took it back to the dealer they replaced my break pads, and told me they had to spray a special lubricant on the pads to keep them from squeeling, of course the sound came back.
The way I get rid of it is accelerate, break really hard and the sound goes away for a while, but it does come back. Its annoying but I do not know what to do.
The funny part is that this noise only appears when you are almost at a full stop.
