I have 2002 BMW E46 330xi, it had some issues with vibration at idle (in drive or reverse). I have changed all 3 mounts plus new original nuts (2 for engine and 1 transmission mount). Tranny mount was badly damaged, engine mounts - just sat i little bit lower than new ones. All mounts are from OEM manufacturers for this part - Lemforder for tranny\Corteco for engine mounts. After changing mounts vibration became even worse when in gear, I can hear front passenger door rattle when idling at R. There is no errors with DME\TCU, CV axles were rebuilt less than 200 miles ago, transfer case was replaced with lower mileage one.
