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?
