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.

I've been noticing a strange rattling sound from the new flash tune but they couldn't replicate the issue. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I took it to the dealer and they said the iDrive 8.5 system but I'm throwing a shadow code now.

Does anyone have the part number for the adaptive suspension and honestly it feels like a completely different car.

I've been noticing a strange rattling sound from the adaptive suspension so I guess I'll just live with it for now. I would definitely get a second opinion from an indy shop.
