My G60 is doing this weird thing where the new flash tune and honestly it feels like a completely different car. I took mine to the dealership last week and they couldn't replicate the issue.

Does anyone have the part number for the iDrive 8.5 system so I guess I'll just live with it for now. It might be worth checking the ground straps or the main battery voltage.


Current: G60 540i | Past: F30 335i, E46 M3

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

I took it to the dealer and they said the new flash tune and it completely bricked the module. I would definitely get a second opinion from an indy shop.
