    Thermostat issues would mean the temp would nopt get hot... over heating is norm alloy a failed water pump...

    CTS failure (in my experience) doesn't over read... if you are seeing 110 deg then I suspect its the pump...

    Thanks guys, if it was sensor would it read on vagcom??
    Just took out now it gets to 110 very quick and then 120 and stays on there? Could it be head gasket possibly?

    Does sound like it could be the water pump, do you know if its been changed as they do tend to break the fins off, I wouldn't be driving far if this is the case as you could do more damaged with it overheating

    Not easily... do you know if the cam belt has been done and if the water pump was changed at the same time?

    When the engine is cold you could take the top off where the antifreeze goes in and get someone to rev the engine, have a look and see if there is any movement in the water, also see if the pipes to the radiator get hot, but from what you say about getting hot very quick it does sound like the water pump, it should always be changed same time as cambelt, I did mine after only 50k and it looked rough

    that'll be because your water isn't being circulated around the engine because of your broken pump. Therefore the heater matrix never gets hot and therefore the air that gets blown over it never gets hot??

    I know this is a silly question, but have you checked that the engine is actually that hot? and is fan kicking in etc?
    Ive had a lot of problems with: Fuel gauge, rev counter, speedo, lcd screen and temp gauge (same sorta problem as yours). Its all to do with a faulty Instrument Cluster.
