New 2012 528i - road noise
 

Hi guys,

I just purchased a 2012 528i with CPO 35k on the clock. I noticed that there is what I consider excessive road noise from the front left. Almost sounds rhythmic like a tire out wheel out of balance, however nothing gets transmitted back to the steering wheel.

Dealer claims tire (Conti run flats) are in spec with some light feathering. There is minimal noise from the other 3 corners.

I'm thinking the following:

1. Imperfection in tire
2. Bad wheel
3. Bad wheel bearings

Being new to BMW and Run Flats, looking for a little advice on where to look and how to get this sorted.

Thanks in advance.

Mike
