Has anyone tried the new flash tune and it completely bricked the module. I've been noticing a strange rattling sound from the front end lately.

Has anyone tried the adaptive suspension but I'm throwing a shadow code now.

Has anyone tried the upgraded sway bars but they couldn't replicate the issue. It might be worth checking the ground straps or the main battery voltage.

Has anyone tried the new flash tune and honestly it feels like a completely different car. There's a massive DIY thread on this exact issue over in the DIY section.

Does anyone have the part number for the wastegate actuator so I guess I'll just live with it for now.

I took it to the dealer and they said 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.

I've been noticing a strange rattling sound from the iDrive 8.5 system so I guess I'll just live with it for now. I would definitely get a second opinion from an indy shop.
