I need some help here from the fellow M2 owner who has disable the fake engine sound using bimmercode or similar device.

My understanding is that turning off ASD using the bottom in the center console does not turn off fake engine sound completely, fake sound are in "Reduced" state. It still produce a low hum through the speaker all the time. Please correct me if this is wrong.

M2 is my daily driver, and I drive on highway 30min-1hr at times, hearing the hum and drones for that long kind of bothers me. My old A4 was best for highway cruising, stable and quiet, but a bit boring to drive.

Even the GR86 seems to be less noisy than M2! But that's can't be, right?? M2 suppose to be a luxury sport coupe, where GR86 is a econobox sport coupe!!!

I am not a big exhaust sound guy, I like to open the window and hear the sound when I want to, and close the window and enjoy the luxury interior and the excellent performance of my car.

So I am hoping the fake engine noise is the cause of the problem.
For those that have it turn off, what is your opinion?
Are they still loud and noticeable in "Reduced" mode?

To be honest I only hear the fake noise when near WOT with windows up. I mainly drive with windows down so its not an issue.

Bugged me on my past F80/82s, non issue for me on the current M2. Maybe I’m just used to it now years later. Seems like everyone is doing it in some form or another.

I like when companies use the sound tube instead of the speakers. Easy enough to remove and plug the holes and not have to worry about anything software related.

I used BimmerCode to turn it off and don’t notice any noise. Pretty sure you have to go to expert settings to actually turn it off fully.

It’s not intrusive compared to the f8x gen. Just cruising around you won’t really hear it even with the sound button pressed. Without the sound button pressed I can’t hear it at all. At WOT I actually quite like it, without it the car is super quiet even at redline. If you want exhaust but no ASD, you can get a valve controller for $300. The exhaust never fully opens under stock programming so you will want that anyway.

I don't hear it at all on the highway. I switch to the Efficient engine mode, and I'm not even sure if it's on or not. I use Sport+ when driving around town in the lower gears, and I like what I'm hearing. To me, it sounds like it's mostly coming from the exhaust, if not fully, and I like it.

the active sound was the worst I've experienced in a bmw. had mine coded off immediately. on street my valves are usually closed and it's pretty quiet. valves open and its just right. no drone.

Very glad I was able to code out ASD on the 2025 iDrive 8.5. See ya!

thanks for the response!
did you code it out in expert mode with bimmercode?

some post earlier said it is not noticeable, what do you think?

thanks in advance!

My own experience is that the cabin button does not ever completely turn off 'fake sounds' or ASD. I had the same concern that I still heard residual noise, so I did completely code out ASD using Bimmercode. This makes a significant difference even compared to the "sound off" option using the centre console button. So I guess in answer to the OPs question, no the button does not completely disable ASD.

I looked up a post on how to do this in Bimmercode, will try to find it and link if needed

[mike@x-ph.com]

One of the first things I did was get bimmercode and remove te fake sound. its so annoying and cheesy

[Ravenseal]

I don't notice fake engine sounds since getting a midpipe.

[G87DRVR]

You have to disable lots of items in Expert Mode in Bimmercode. My car went silent after doing this. Wednesday my midpipe and SST Controller will be installed so I am curious how it will be after that..

[laughMan]

thanks for all the response!!
sounds like i will have to try to code it out and hear it myself to see if it is significant to me.
