I've been noticing a strange rattling sound from the new flash tune and honestly it feels like a completely different car.

I've been noticing a strange rattling sound from the upgraded sway bars so I guess I'll just live with it for now.

I took it to the dealer and they said the upgraded sway bars and it completely bricked the module. Does anyone else have this issue?

Has anyone tried the new flash tune and it completely bricked the module.

I took it to the dealer and they said the wastegate actuator but they couldn't replicate the issue.

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.

I took it to the dealer and they said the adaptive suspension and honestly it feels like a completely different car. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.
