Hello everyone, my 330e started to make a squeaking noise when accelerating NOT when braking, only accelerating. I've been to dealer 4 times, first two they claimed its brake pads and emergency brake, next time they said they dont know the cause and the final time said its a normal noise. I am going in again to a different dealer but wanted to see if you guys are familiar with the noise. Car at 36k miles right now, started a few thousand back. Video below

thank you!

i recall some youtube video about a handbrake cable sagging underneath the car and rubbing off something. required a cable tie to temp fix it.
Couldnt find the video though.

I have a similar sound when accelerating and at low speed arround 20-40km/h , not during braking!I hear it only in electric mode and haven't dealt with it because I don't believe the dealer will manage to find the source of the problem .
I will try to get a video but I believe we should live with it since it doesn't seem to be a real problem.

I was having this issue as well. I had it serviced and they found that it was the Parking brake. Mainly debris between the rotors and rear brake shoes. I hope this helps you guys.

Problem solved after having rear brake pads and rear wear sensor replaced.My mechanic said it must have been the sensor making that noise.

I have the same issue as well.. it's so annoying what was the root cause?

The brake pad wear sensor was rubbing the metal: was not replaced with the previous pads, or was misaligned, or your current brake pads are worn down so the sensor started to do its job.
