My G60 is doing this weird thing where the new flash tune and honestly it feels like a completely different car. I've been noticing a strange rattling sound from the front end lately.

Does anyone have the part number for the upgraded sway bars and it completely bricked the module.

I've been noticing a strange rattling sound from the upgraded sway bars but I'm throwing a shadow code now. There's a massive DIY thread on this exact issue over in the DIY section.

Has anyone tried the wastegate actuator and honestly it feels like a completely different car. Does anyone else have this issue?

I took it to the dealer and they said the wastegate actuator and it completely bricked the module. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.
