Vag com can indeed help a bit. Go into the gateway (19?) and check measuring blocks 125 upwards. 125 to 127 are for the powertrain bus IIRC. It will list each control unit on the bus and have a 1 if it can communicate with the unit or a 0 if it cant.
The instrument cluster connects directly to the CAN gateway - it is seperate from any other bus. Interesting how it will start with the cluster disconnected though as it has the immob. built in.
Would be interested to see a complete vehicle scan, and some scope traces.
