with the car running just after startup from cold do u see a stream of water flowing into expansion tank,if no water flowing
suspect water pump impeller broken,plastic blades that move water around engine,common problem with vw .it is normally all replaced when replacing timing belt.
if u can also check water hoses going in thru bulkhead to see if good and hot.

Thanx i will check this out when he next comes round, i would of thought this was ok as the heater matrix pipes do get warm so the water must be flowing but i will try expansion tank
