In my case it's 18". One of the summer tires sets could have been 17" but not sure. I also tried a 320d Touring 2019 from the dealer, and there were no issues found here.
I thougt that it could be the front diff at first but I see that you got the 2wd? So it must be something else.
Yes. I only have 2wd.

No - those were 17"
Is your moonroof tilted? I only hear the sound from the drivers window when I have it on tilt makes no sense but that's what I have discovered so far

Hi guys,

New to this forum.

Ended up here after some googleing since my brand new 2020 330d touring xdrive m-sport seem to have the same wind/road noise as described in this thread.

My perception is that the noise is coming from the right hand side foot well.

My car is on studded 18" 224/45 tires and is equipped with acoustic glas.

I do not belive the noise is from the tires since my previous car 2017 330d xdrive m-sport did not make such a noise on studded tires. The noise varies with speed. The noise is noticeable from about 50 km/h and up, around 130 km/h it starts to get really annoying.

I hope someone will find the cause of the noise. I will be visiting the dealer next week and let you know what happens.

I don't think it is the tires, but i think that different wheels can reenforce the noise, and the 18" m-sport wheels seems to be the most common here and probably the worst? It would be interesting if anyone who have 19" also have this noise.

It seems like we are a bunch of guys that all have the same problem. Do we all have the M-Sport version with M-Sport brakes and Sports transmission?

I'm just trying to find a pattern here ;-)

Morning..

So, I've noticed the wind/grinding noise is also present in idle now! I opened the hood and it sounds like its comming from the area around the turbo!

I have recorded it on a video. Turn your volume up to hear it.

Very good find, also the video, thanks!

Although I doubt it is the turbo itself, as in my case the pitch of the sound stays the same regardless of revs, also the volume is pretty much constant.

I am very curios now what could be the culprit. And I'm starting to worry that this might be considered by BMW as a "normal" engine sound (though I hope I'm wrong).

I don't think that mine noise have something to do with the engine. I'm quite sure that it has something to do with the transmisson or bearings. I can't hear it when the car stand still.

I can't really hear the sound in the cabin when holding still either. But if I pop the hood I have the exact same noise from the engine from outside. Wether this is a "normal" sound from the engine or infact the culprit we are looking for, I'm not entirely sure of.

I doubt it is the same because I have a 320d

I did the same today and I also have the same sound at idle. So strange because I got a 320 diesel. Maybe it's servosound? Or it could be the turbo but than it's not the sound I hear at speed because that sound doesn't follow the revs.

Could it be the gearbox?

I have had a talk with my dealer and my tire guy, the dealer acknowledged the noise and is willing to take the car in for troubleshooting. Their first action would be to try a different set of tires.

My tire guy who sold me my studded Continentals said that is not uncommon for tires to need a break in period before they quiet down. He recommended me to run them for 3000-4000km before any other troubleshooting.

Hopefully the run in will be enough, I will try that first and report back in a couple of weeks if the noise hasnīt gone away.
