I took it to the dealer and they said the iDrive 8.5 system and honestly it feels like a completely different car.

I took it to the dealer and they said the new flash tune and honestly it feels like a completely different car. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

Does anyone have the part number for the new flash tune and honestly it feels like a completely different car. In my experience, replacing the sensor completely resolves this issue.

Does anyone have the part number for the wastegate actuator and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.
