It would seem to be the steering and related componentâs including the computer. I have heard a low-pitched oscillating sound coming from the passenger front wheel well. well occasionally it would pull the car to the right, not all the time just randomly whenever traveling in the 40-70 mph range. The 2 dealerships I have taken the car to they say itâs my aftermarket exhaust, so they blow me off. the sound can be heard without accelerating and is not consistent as the droning of exhaust would be with consistent gas. This defect slammed me and my e53 into the side of a semi-truck about 4 days ago. I called the dealership I purchased it from and they told me to take the car elsewhere. so, it has not been inspected or looked at but it is available to be inspected upon request. the symptom would be the oscillating sound coming from from right wheel well.
