8 Series Audio Bug

My July delivered 850 coupe has developed an irritating audio bug. You will see from the video it is a high pitched sound, which gets louder as I accelerate. It also distorts all other sounds, such as music and the reversing sensors.

Stopping the engine and restarting does not reset the problem. Leaving the engine off overnight appears to temporarily stop it. It starts again randomly.

Anyone else have this issue, or know how to fix it? I presume it is coming from the augmented engine sound software.

Ozzie, I have seen one other report of that, either here or on another message board. I never saw a confirmed cause. (Small consolation, I know, but misery does love company. Also, if others have experienced and reported this to service technicians, a fix already may be in BMW's service data base.)

An interesting update on the audio bug.

Yesterday my 850i went into BMW for investigation. Full checks undertaken. According to the service agent there is a known audio issue and they applied the appropriate software update. I guess time will tell if the issue has been fully resolved.

But something else quite wonderful happened. As you may have read in some of my earlier posts I was underwhelmed with the Bowers & Wilkins sound system, especially when compared to the Bang & Olufsen in my old 6GC. Well not any more.

All of a sudden I've got sub woofer doof doof! And what a difference it makes. Before the update I just could not get the depth of sound going in the car and put it down to the B&W not being as good as the B&O. Sorry B&W, it was the car all along!

Good to hear hopefully your gremlin is history and the fact that the software update applied finally opened up the bass range. Fingers crossed that my 2020 M850i order w/ B&W audio landing in early December (it is scheduled to hit the Long Beach port on the 11/28) will already have the latest software. However, if bass is lacking I'll definitely be having a conversation with my dealer.

Any chance you can ask what specific software update was applied?

bloozemanAZ I did ask BMW for more details on the software update so I could post technical details for the forum, I will post when I receive.

Congratulations on the purchase of your m850i - you are going to love it mate - it is a fantastic car - it will make you smile every time you press the start button. Post photos.

Software upgraded to version S18A-19-11-530.

Thanks! Received an update from my SA today that the ship did land two days late (30th) so now the car is going through customs, VPC and ultimately put on an auto transport to my dealer. The good news being that once it hits the auto transport that is 2 days tops (should be 1 but not sure of the route and stops along the way) to make it here to AZ.

I did check out a M8C in Davit Grey with Silverstone interior at my dealer over the weekend. Gorgeous car and comparing it to my 1st order in Davit Grey and Fiona Red/Black interior that is also at my dealer I like the M850i's interior better (cleaner design vs the waffle grid) and honestly cannot justify the $ differential for my needs.

Thanks for the info and going to make sure that is on my M850i before I take possession!

I remember the feeling when my car was days away after a 9 month wait! Enjoy it - the car has unlimited effortless power for any non-track situation.

Couldn't you download the software over the air or it had to be done through the dealer?
