Could be air locks in the system, or it could be a small leak.

I had problems with the heater valve weeping, replaced it witha MK1 Golf one about £7 quid from GSF.

I had a distorted swan neck doobery that the cap fits. New cap did not make a difference. So a little modification () until my new neck arrived. Check the seat is flat (if that makes sense).

i take it the fan is running? Obviously at standstill there is no air flow to cool radiator. Maybe the impeller of the water pump is shot, therefore not pumping enough water to the radiator.
