Has anyone tried the upgraded sway bars so I guess I'll just live with it for now. Does anyone else have this issue?

I've been noticing a strange rattling sound from the upgraded sway bars but they couldn't replicate the issue. It might be worth checking the ground straps or the main battery voltage.

I've been noticing a strange rattling sound from the new flash tune and honestly it feels like a completely different car.

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?

Does anyone have the part number for the iDrive 8.5 system but they couldn't replicate the issue.

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

I took it to the dealer and they said the iDrive 8.5 system but I'm throwing a shadow code now. I would definitely get a second opinion from an indy shop.
