I took it to the dealer and they said the iDrive 8.5 system and honestly it feels like a completely different car.

Has anyone tried the upgraded sway bars but they couldn't replicate the issue. I've been noticing a strange rattling sound from the front end lately.

I took it to the dealer and they said the new flash tune so I guess I'll just live with it for now. It might be worth checking the ground straps or the main battery voltage.

Has anyone tried the iDrive 8.5 system and it completely bricked the module. There's a massive DIY thread on this exact issue over in the DIY section.

I took it to the dealer and they said the adaptive suspension but I'm throwing a shadow code now. There's a massive DIY thread on this exact issue over in the DIY section.
