Whining sound at low speed

AndyLu · 09-05-2018, 01:46 PM

Does everyone's car make a slight whining sound when going slow speeds? Sounds like a siren/whine sound.

Sounds starts around five seconds

Oh yeah it does it under load or in neutral

Fast4d · 09-05-2018, 02:20 PM

DCT or manual?

if in neutral and engine at idle might be the diff.

Yeah car is in neutral, stand still and makes that noise.

Here is another video. Sorry about the fire truck.

BTW, is that normal for the diff to make that kinda noise?

Any chance you could make a longer video? This time with as little ambient noise as possible, first half window up second half window down. tbh, I think I hear what you might be talking about but there's so much racket in those videos that I can't be sure. For now however I can tell you that I don't have any "whining" sounds at all. (16 DCT)

Will do in the morning. Dropping my car off tomorrow for something different but will talk to my sa about this as well

If you bring up the noise issue with the SA, do let us know what he has to say.

I was scared he was talking about the turbos.

mfurse · 09-06-2018, 05:50 AM

Mine makes this faint whining noise. It's coming from the engine - I put it down to intake noise? Seems so subtle and no vibration or anything. I might get the dealer to swap the diff fluid out next service see if its that.

Darth One · 09-06-2018, 06:39 AM

I posted a thread in the GTS subforum before seeing this. I have a similar noise that's been diagnosed as differential noise, and supposedly normal. Mine is not anything I'd describe as 'slight', though. It's quite loud and gets much louder with throttle input. But then again, the GTS supposedly has much less insulation than the normal M4.

It's all fine by me if there's nothing wrong with the car. The dealer said everything checks out, so...

Fast4d · 09-06-2018, 11:54 AM

well if it happens at a stand still while reving...take a listen under the hood.

belt tensioner pulley bearing? a/c pulley/clutch? turbos bearings?

AndyLu · 09-09-2018, 01:46 PM

Sorry been busy all week. Car is with the dealership. But I have another video

This guy mentions it in the review of the M6 in the video below at the 7:18 point:

Just say much other than an annoying noise. I might see if I can take a new m out and see if it does that same type of whine

WedgeSalad · 09-10-2018, 10:24 AM

Just test drove a 2018 m3 with comp and it made the whining noise. When asked the dealer said it was the brakes making the noise.

I know what the breaks sound like but this happens at stand still

AndyLu · 09-11-2018, 02:26 PM

If everyone is having this type of noise I would take it to the dealership. My SA told me it's the idler pulley.

Just got back from a trip and listened to this video. Mine defiantly does not do that or anything even close. Thanks for the subsequent post regarding the idler pulley, I'll certainly keep that in mind. So I assume you're having that taken care of under warranty, please let us know the results. Thanks.

AndyLu · 09-13-2018, 08:00 AM

Just got my car back. No more whining. Sounds just like it did before. Feels good to be back in my car.
