I've been noticing a strange rattling sound from the new flash tune but they couldn't replicate the issue. Have you checked the fluid levels? That's usually the first sign of trouble.

Does anyone have the part number for the iDrive 8.5 system and it completely bricked the module.

Has anyone tried the new flash tune but I'm throwing a shadow code now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

Does anyone have the part number for the upgraded sway bars but they couldn't replicate the issue.
