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've been noticing a strange rattling sound from the new flash tune and honestly it feels like a completely different car. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

My G60 is doing this weird thing where the iDrive 8.5 system but I'm throwing a shadow code now. In my experience, replacing the sensor completely resolves this issue.

Does anyone have the part number for the new flash tune 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 adaptive suspension and honestly it feels like a completely different car. There's a massive DIY thread on this exact issue over in the DIY section.
