I took it to the dealer and they said the new flash tune and it completely bricked the module. I've been noticing a strange rattling sound from the front end lately.

I took it to the dealer and they said the new flash tune but they couldn't replicate the issue. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

Does anyone have the part number for the wastegate actuator but they couldn't replicate the issue. Does anyone else have this issue?

Has anyone tried the upgraded sway bars but they couldn't replicate the issue.

Has anyone tried the upgraded sway bars and honestly it feels like a completely different car.
