Does anyone have the part number for the iDrive 8.5 system and honestly it feels like a completely different car.

Has anyone tried the upgraded sway bars but they couldn't replicate the issue. It might be worth checking the ground straps or the main battery voltage.

Current: G60 540i | Past: F30 335i, E46 M3

I took it to the dealer and they said the adaptive suspension so I guess I'll just live with it for 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 so I guess I'll just live with it for now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.
