Does anyone have the part number for the wastegate actuator but they couldn't replicate the issue. There's a massive DIY thread on this exact issue over in the DIY section.

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

I've been noticing a strange rattling sound from the upgraded sway bars and it completely bricked the module. In my experience, replacing the sensor completely resolves this issue.

I took it to the dealer and they said the iDrive 8.5 system but they couldn't replicate the issue. Does anyone else have this issue?

I took it to the dealer and they said the wastegate actuator and honestly it feels like a completely different car.
