if your mucker is doing a lot of miles then the fan shouldn't be a worry as the fan is for when the car is stood in traffic and the rad wont get cold air forced through it. just change the temp senders.
As for the stat have you got the right one fitted? change that for a new one, they dont cost that much.
is the rest of the engine ok? when was the engine last serviced? does the engine reach running temp very quickly? could be that the problem is agriveted by a hot running engine.

Make sure you buy a genuine VAG thermostat, and make sure you get the right one!

i chyanged the thermostat with a new vag one, new sensor in therad too.
i no the thermostat dont open till late as i sat watching the temp gauge in the car, once the temp reached almost top temp it dropped down so i went checked the bottom hose on rad and it started getting warmer, then the engine took abt ten more mins(engine temp now past proper hot mark) before fan kicked in, took temp down to just over 3/4 before doing the same again.

im thinking that the gauge on the dash is reading wrong, thats why i asked abt that last sensor that controls the temp gauge in the car

i take it he doesnt have an MFA so he can check oil temp against water temp?

seems quite bizarre indeed!

all sorted now, turned out to be the sensor that tells the dash wot temp its running at, so the engine wasnt running hot after all,  :-[
dont i feel stupid telling him it was probably the thermostat or fan switch, but then for 320 quid wot do u expect lol   ;D
