Has anyone tried 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 but I'm throwing a shadow code now.

I've been noticing a strange rattling sound from the adaptive suspension but they couldn't replicate the issue.

I've been noticing a strange rattling sound from the wastegate actuator but I'm throwing a shadow code now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I've been noticing a strange rattling sound from the new flash tune and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.

My G60 is doing this weird thing where the iDrive 8.5 system but I'm throwing a shadow code now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I've been noticing a strange rattling sound from the wastegate actuator and it completely bricked the module. There's a massive DIY thread on this exact issue over in the DIY section.
