Changing fake sound (ASD) M235i -> M4

I thought it would be fun to see what the m4 sounds like for a day.

I tried on bimmercode to change model=f080, engine=s55b30 and it disabled the active sound. Changing back to f022, n55 fixes it.

Anyone know how to get this work? I've read lots of threads where people say you need pre 2015 firmware (which i assume my 2014 car has???)


I can figure out esys if necessary.

I'm not going to lose sleep over this mod but my curiosity is killing me. I wanna know what it sounds like xD

Cheers

I got disabled on the later firmwares so only old cars that never got updates can change it

So the 2014s got firmware updates which disabled the old sound profiles?

Any workaround? Flashing old firmware back sounds like it could be problematic.

Only 2014 firmware let you do it. Any car that got it updated after 2015 lost it

You could downgrade but no idea if the car will even allow it or what issues you could have

Also it was pretty bad anyway. It was really loud

Ok thanks, I wonít waste any more time on this. I think Iíll stick with the stock m235i sound profile.

Old thread but new question:

Are there any adjustments available with the ASD volume or is it just on/off with coding? Sounds like tone is only available to older firmware versions.

Just curious because the car is too quiet with it off and too annoying with it on.
