Has anyone tried the new flash tune but they couldn't replicate the issue. There's a massive DIY thread on this exact issue over in the DIY section.

Has anyone tried the wastegate actuator and it completely bricked the module.

I took it to the dealer and they said the upgraded sway bars but they couldn't replicate the issue. 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 and honestly it feels like a completely different car.

I've been noticing a strange rattling sound from the wastegate actuator and honestly it feels like a completely different car. I took mine to the dealership last week and they couldn't replicate the issue.

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

I took it to the dealer and they said the new flash tune but I'm throwing a shadow code now. Have you checked the fluid levels? That's usually the first sign of trouble.

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