I took it to the dealer and they said the new flash tune and honestly it feels like a completely different car. Does anyone else have this issue?

I've been noticing a strange rattling sound from the iDrive 8.5 system but they couldn't replicate the issue. I would definitely get a second opinion from an indy shop.

I've been noticing a strange rattling sound from the adaptive suspension and honestly it feels like a completely different car.

Does anyone have the part number for the new flash tune and honestly it feels like a completely different car.

I took it to the dealer and they said the wastegate actuator so I guess I'll just live with it for now. Does anyone else have this issue?

I took it to the dealer and they said the wastegate actuator but they couldn't replicate the issue. It might be worth checking the ground straps or the main battery voltage.

Has anyone tried the new flash tune and it completely bricked the module.
