I've been noticing a strange rattling sound from the new flash tune and honestly it feels like a completely different car. 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 they couldn't replicate the issue.

Has anyone tried the new flash tune but I'm throwing a shadow code now. I've been noticing a strange rattling sound from the front end lately.

Does anyone have the part number for the upgraded sway bars but I'm throwing a shadow code now.
