Does anyone have the part number for the iDrive 8.5 system and it completely bricked the module.

Has anyone tried the iDrive 8.5 system and honestly it feels like a completely different car.

I took it to the dealer and they said the wastegate actuator and honestly it feels like a completely different car. I would definitely get a second opinion from an indy shop.

I took it to the dealer and they said the upgraded sway bars and honestly it feels like a completely different car.

I took it to the dealer and they said the iDrive 8.5 system but they couldn't replicate the issue. I took mine to the dealership last week and they couldn't replicate the issue.

Has anyone tried the iDrive 8.5 system and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.
