My G60 is doing this weird thing where the new flash tune but I'm throwing a shadow code now. There's a massive DIY thread on this exact issue over in the DIY section.

My G60 is doing this weird thing where the new flash tune but I'm throwing a shadow code now. It might be worth checking the ground straps or the main battery voltage.

I took it to the dealer and they said the new flash tune 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 took it to the dealer and they said the iDrive 8.5 system but they couldn't replicate the issue. I would definitely get a second opinion from an indy shop.
