Got the run-in service done today and a bunch of these sound deadening parts came in today as well.
Will be fun to figure out how to put them in.

Well I got shipped some of the wrong parts.
Only got the one side metal plate that goes in the rear side panels around rear seat area.
Instead of the other side I got a box with a wishbone lol.
And I got sent the wrong plugs for the wheel well insulation.

Will sort these out tomorrow.

So far I only have the door to fender insulation and the engine bay under hood piece installed.

That’s too bad. How’s the difference with the pieces you have installed?

Honestly it's a lot quieter in the car now with just the bits I have installed.

Suspect that the winter tires were responsible for a good part of road noise. Now with the summers I'm second guessing the need for all those other pieces. I'll do them anyway for highway trips.

Been the opposite for me. I'm running PSS's they are way louder that the snows.
They are 155 and 175's too so either than stock.

Interesting you meant 255 and 275 mm width?

I forgot, do you also have the MPE?

Voyagergab do you have pictures of the pieces you’ve installed or will be installing and where they go? Are you on PSS?

Yeah I'm on stock PSS tires that came with the car new 2, just installed them a couple of weeks ago.

Sure I'll take pics of all the parts tomorrow.

GregoryK Thank you for being the pioneer for this project and sharing the info with us.

voyagergab Are you able to confirm whether the side hole covers (41007294289, 41007294290) are already in place for M2?


I am less bothered by the road noise but the (non-MPE) OEM exhaust drone at constant speed does get to me quite a bit. I plan to do the 4 rear wheel well insolation pieces as well as the covers if needed. Are you guys getting the parts from your respective dealer or online? Thanks!

Based on GregoryK 's findings those 2 side hole covers are missing in the M2. So far I only received just one of them and waiting for the other one from my dealer. Then I'll take the trim down to check if there are missing indeed from my car as well.
And yes I ordered all these sound deadening parts from my local dealer.

Yes, thank you GregoryK & voyagergab for sharing your findings.

RedCarrot is your ASD still active? If so that’s what you’re hearing. It’s very annoying. If you need more info let us know.

Hey Voyagergab. Are those panels for the whole beside the passengers seats metal or hard plastic? If so I think that they would do a better job than the Dynamat that I used.

It is metal. Looks like an aluminum alloy.
Feels pretty substantial.

A soft product will not do as good a job IMHO. That will act like double glazing does where what I did would be like sticking that plastic stuff on the inside of a single glazed window. It would help with heat transfer but would not cut down the noise as much as a hard surface. I'm going to order those parts. I still have a letter into BMW to find out why those parts were missed even though they show up on RealOEM.

Oh I coded ASD out via BimmerCode within the first week of taking delivery. The drone is very distinctively coming from the rear at cruising speed. My ears are sensitive to low frequency noise so it bothers me more than most others. Hopefully the insulation and covers will do the trick. I might even add some sound absorbing pads (those used in recording studio) behind the covers for good measure. Thanks for offering info

Red. There is room in the parcel shelf for some thick foam insulation. The stuff with a heavy backing sheet will give the best results for low frequency sounds...like drones.
I've used the Barrymat BM-1c with incredible results on other vehicles.

Good to hear (pun intended).
What do you think makes the biggest difference?
