My car has a vibration between 50 and 60 mph. Took it to dealer, they balanced all 4 tires and said it was fixed. Its not. I guess they didnt test drive it. Anyone ever get this?

I had the same issue with mine, but at about 60-70 mph, especially when getting off the highway under light braking down the exit ramp.

I didn't think much of it in the beginning because it was so slight and I was so full of adrenaline. But I knew something wasn't right.

One time at the dealer for regular maintenance, I mentioned it to the service manager and they took a look at it. They came back to me saying the rotors were warped. wtf? The car had never been on a track or otherwise pushed to its limits. OK, but the brakes have only 12k mile warranty and I was at 13k. fcuk. But they said they would covers parts if I paid the labor for new ones and I went ahead and did it. Cost me about $350.

In the end, it still shakes but somewhat less than before. The mph shake-band has been reduced from 60-70 to 62-65 but it still shakes ever so slightly. I've had new tires put on (from the OEM Pirellis to M-PS) and regularly check the tire pressure so I'm not sure what to blame.

It's such a minor little annoyance that I'm not bothered to do much else about it but I would really like to know how such a highly tuned car could have such a Yugo-esque problem.

Forgot to mention I am driving a B7 RS4

It doesnt happen when i brake. My friend is a mechanic, he said he will take it for a ride. He said if its not a bent rim, it could be drive shaft related.

Mine happens between 80-90mph but it is more a resonance/drone through the chassis than vibration in the steering wheel...i drove the service forman in the car to show the problem. They are ordering me a new rear differential but not arriving until next week. Will keep you posted
