Software Revert ???

Hey Yall, recently my car got updated 2020 M340i updated at dealer without my knowledge to update 7/2021.40 and my car feels a lot slower, less torquey but the most obvious thing is the sound. No loud pops and burbles, no upshift bang like before. Cold start is also quieter now. Really fckin sucks and I dont know what to do. Anyone possibly know of someone or somewhere It can be reverted without losing out o warrranty?

You're screwed buddy. If you want to retain warranty not much you can do. A tune is your only hope man. Sorry for your loss.

*still on 11/2019.70 and lovin it

2020 M340 Xdrive, July 2019 build, has all the updates along the way. Currently 7/2021. No changes no sound, performance or exhaust pops and burbles. Not saying that others don't have issues but I do not

Ya, just had mine updated when I was in for the brake system recall. I was pissed at first cause it sounded and felt so weak, but I once I set sport individual back to sport+ tranny & engine, was all good again. Can't say I've noticed any difference in performance or sound with newest version.
