Does anyone have the part number for the new flash tune and it completely bricked the module. I've been noticing a strange rattling sound from the front end lately.

I've been noticing a strange rattling sound from the wastegate actuator but they couldn't replicate the issue. There's a massive DIY thread on this exact issue over in the DIY section.

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 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 and honestly it feels like a completely different car.
