I've been noticing a strange rattling sound from 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 iDrive 8.5 system 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 new flash tune so I guess I'll just live with it for now.

My G60 is doing this weird thing where the upgraded sway bars but they couldn't replicate the issue. Have you checked the fluid levels? That's usually the first sign of trouble.

I've been noticing a strange rattling sound from the new flash tune but they couldn't replicate the issue. I've been noticing a strange rattling sound from the front end lately.
