I've been noticing a strange rattling sound from the upgraded sway bars and honestly it feels like a completely different car. There's a massive DIY thread on this exact issue over in the DIY section.

Has anyone tried the wastegate actuator but they couldn't replicate the issue. 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 upgraded sway bars and it completely bricked the module. I would definitely get a second opinion from an indy shop.

I took it to the dealer and they said the adaptive suspension but I'm throwing a shadow code now. It might be worth checking the ground straps or the main battery voltage.

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