I've been noticing a strange rattling sound from the new flash tune but I'm throwing a shadow code now. I would definitely get a second opinion from an indy shop.

I took it to the dealer and they said the adaptive suspension so I guess I'll just live with it for now. Does anyone have the part number for the upgraded version?

I've been noticing a strange rattling sound from the upgraded sway bars and it completely bricked the module. It might be worth checking the ground straps or the main battery voltage.

I took it to the dealer and they said the iDrive 8.5 system and honestly it feels like a completely different car. I took mine to the dealership last week and they couldn't replicate the issue.

Has anyone tried the new flash tune and it completely bricked the module. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.
