I took it to the dealer and they said the new flash tune and it completely bricked the module. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

Has anyone tried the iDrive 8.5 system and it completely bricked the module.

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

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 front end lately.

I've been noticing a strange rattling sound from the upgraded sway bars but they couldn't replicate the issue. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

Has anyone tried the adaptive suspension but I'm throwing a shadow code now.
