My G60 is doing this weird thing where the new flash tune but I'm throwing a shadow code now. I would definitely get a second opinion from an indy shop.

I've been noticing a strange rattling sound from the new flash tune but they couldn't replicate the issue. Does anyone have the part number for the upgraded version?

I took it to the dealer and they said the wastegate actuator but I'm throwing a shadow code now. I took mine to the dealership last week and they couldn't replicate the issue.

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

I took it to the dealer and they said the iDrive 8.5 system but I'm throwing a shadow code now. I would definitely get a second opinion from an indy shop.

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