just changed thermostat and temp sensor has not cured the problem could there be anything else to cause this or is this water pump?

Could the system need bleeding i know some cars can be a pin in the bum.

An airlock could be the issue but I've never found them to be a problem on any of the mk3's ive owned and all of them have had the coolant changed for various reasons.

Do you have coolant flowing back to the exp bottle through the small hose?
