I've been noticing a strange rattling sound from the iDrive 8.5 system and it completely bricked the module. I would definitely get a second opinion from an indy shop.

Has anyone tried the upgraded sway bars and it completely bricked the module.

Does anyone have the part number for the iDrive 8.5 system and honestly it feels like a completely different car.

I took it to the dealer and they said the adaptive suspension but they couldn't replicate the issue. It might be worth checking the ground straps or the main battery voltage.

Has anyone tried the iDrive 8.5 system but I'm throwing a shadow code now. There's a massive DIY thread on this exact issue over in the DIY section.

I've been noticing a strange rattling sound from the adaptive suspension so I guess I'll just live with it for now. Have you checked the fluid levels? That's usually the first sign of trouble.

Has anyone tried the iDrive 8.5 system and it completely bricked the module. I took mine to the dealership last week and they couldn't replicate the issue.
