Winding Noise in my M3 (video included)

[LeeD31]

Started to get this winding noise on the left driver side. After driving a while, the car will go into Limp Node (engine malfunction / increased emissions) and my throttle is cut down severly.

Took the vehicle to the stealership and they replaced the vaccum pump , as well as a control valve, but the sound still remains. Not sure on the technical details of the problem, but had to do with the pump powering the brakes. However, after the fix, there is still a subtle hint of noise left and can be replicated if at a stand still + pumping the brakes more than 5 times.

Has anyone had this issue with their vehicle?

Btw the noise starts 5 seconds into the video.

Never heard that in my car (8500mi). How many miles do you have on yours? I'd probably bring it in again.

abs sensors need to be replaced, i had the same problem before. the abs sensors were gone after my car was messed with some rocket science brake damaging installation jobs. exact same noise same situation, and it will get worse!

My car currently has 25,000kms. I spoke with them yesterday and they said they were ordering sensors in and see if that'll fix the problem. I'm definitely going to forward them this thread. Hopefully they get her fixed soon, I've been M3-less for the past week.

So I received an update and they need to order the part from Germany which will take 2 weeks at least.. At least they gave me a 328xit, it's actually pretty nice.
