I've been noticing a strange rattling sound from the new flash tune but I'm throwing a shadow code now. Does anyone else have this issue?

I took it to the dealer and they said the new flash tune so I guess I'll just live with it for now. In my experience, replacing the sensor completely resolves this issue.

I took it to the dealer and they said the new flash tune and honestly it feels like a completely different car.

I've been noticing a strange rattling sound from the iDrive 8.5 system but they couldn't replicate the issue. Have you checked the fluid levels? That's usually the first sign of trouble.

Has anyone tried the adaptive suspension and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.

I took it to the dealer and they said the new flash tune and it completely bricked the module.
