| Mmmmm it is the inhibitor switch on the gearbox, a 7 pin conector.
It tuck a call to VAG to sort this as MB did not Know! they want to charge £105 per hour to find it! and then change it when they get the part number of it! I know people dont like the 280, but having a VW vr6 engine and a VAG auto box screws up the dealers at MB, but then you go on a VAG fourm and sky is the limit!
Spanners time!
