Hey everyone, I have a 2020 RWD M340i, and I recently upgraded it with a stage 2 e50 tune using BM3. I've noticed that after the tune, my car seems to rev up a tiny bit by itself while idling, even though the RPM gauge doesn't show any change. This has been happening for a few weeks now, and on top of that, a few days ago I got a random drivetrain malfunction code that seems to appear after a few minutes of driving.

I just placed an order for new spark plugs and ignition coils, just in case they are causing the problem. About a week ago, after doing a burnout, each cylinder in my car misfired, which makes me wonder if it's related to the other issues.

Below, you'll find videos/pictures illustrating everything discussed above. I'm mostly worried about the weird idling, the drivetrain malfunction warning, and the rest of the diagnostic codes I got when scanning my car. If anyone has experienced similar issues or has any advice, I'd really appreciate your help!
