Mini-me (Mr. Bishop) had a similar prob in his old Zetec-S Fiesta which would only get hot on the motorway, trundling around it was fine. Water pump cured it.
Hope you're ok anyway dude!
could well be mate! it is due a cam belt change so this could be on the cards sooner rather than later now. it sits at about 105c and half way on the gauge at idle! only when driven it goes up! its been to 132c but fans kick in at 122c all logged from the ECU with OBD reader with new sensor.
Yeah all well and good mate! Should of thought to give you a shout on the old FB. Hope all is well with you too! Get that Golf back on track!!

water pump + Aux belt, thermostat and housing, head gasket, temp sensor, new rad, in car heater was hot so that rules out an airlock if what I was told is true,
nothing cured it.
Only place its going with current mileage and condition is the scrap yard sadly so he is keen to save it! will see what a waterpump does for it as it is due one! cheers

I remember a long topic on here about this a little while ago about exactly the same issues, could be worth a search.
Loom is all ok this is something else i have checked! Another temp gauge isnt a bad shout though to get an idea of what im looking at. It seems a common problem but from what i have read a new sensor tends to cure it or the topics go on for ages with people struggling to find the sensor at all lol

Coolant Temperature °C (°F) CHT (volts)
20 (68) 3.09
40 (104) 2.15
70 (158) 1.04
80 (176) 0.79
90 (194) 0.61
97 (206) 3.51
105 (221) 3.25
