Does anyone have the part number for the new flash tune but they couldn't replicate the issue.

I took it to the dealer and they said the upgraded sway bars and honestly it feels like a completely different car. I would definitely get a second opinion from an indy shop.

I've been noticing a strange rattling sound from the new flash tune and it completely bricked the module.

Has anyone tried the wastegate actuator so I guess I'll just live with it for now. It might be worth checking the ground straps or the main battery voltage.

I've been noticing a strange rattling sound from the iDrive 8.5 system and it completely bricked the module. I would definitely get a second opinion from an indy shop.
