hi ,water temp sensor was fitted to side of block with white block connector (as stated by rubjonny)
Changed this today ,,still the same,, the garage next door has done some checks and they are now convinced that the head gasket is the culprit.so i have left them to change it ,,they are good guys ,so i hope i will get my car back soon and all will be ok.
its been a expensive month,new discs and pads all round,water pump,all the belts,plugs,leads,cap and arm ,,and tax mot and insurance.

good job i am very fond of my golf
