Hi there,

First time poster, long time lurker here. I need help. I have a 2014 320i that has a terrible squealing/whirring noise that seems to be coming from the rear passenger side of the vehicle. The noise has been intermittent since I have owned the vehicle for about 1.5 years. My dealer (BMW of Dallas) has been unable to diagnose or remedy the issue even though I have brought it to them several times over the last year an a half. A Service Manager even took the car overnight to see if they could diagnose the issue, but unfortunately – luck.

A few things you need to know:

- The noise appears more often when the car is not warmed up
- It seems to only happen when I'm coasting with my foot off the accelerator
- I cannot replicate the noise on demand
- The noise is there both in colder and warmer months
- It has become worse over the last few weeks

Below is an audio clip of the noise (it peaks around the 10 second mark):

Any assistance you can provide in helping identify or diagnose the noise is very much appreciated. This has become a point of frustration to me mostly because BMWs stand for quality and this noise is taking away from that. Secondly, the noise can be loud which on some level is a bit embarrassing. Lastly, my dealer cannot seem to help me, so I’m hoping this community can.

Thanks,

Sean

good news is you have 2.5 years of warranty left, these things tend not to fix themselves and get worse over time. Good luck. sounds like a rattle vs a bearing or suspension piece but i am not a mechanic, nor do i play one on TV.
