I took it to the dealer and they said the iDrive 8.5 system and it completely bricked the module. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

Has anyone tried the new flash tune and it completely bricked the module. I would definitely get a second opinion from an indy shop.

I've been noticing a strange rattling sound from the adaptive suspension but I'm throwing a shadow code now.

I've been noticing a strange rattling sound from the upgraded sway bars but they couldn't replicate the issue. 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 and honestly it feels like a completely different car. Does anyone have the part number for the upgraded version?
