    Hi all,

    I have just got a 1.6 Petrol 2001 Audi A3 and it is fine apart from the temp gauge never goes over 70 when driving...but if you leave it idle it will go up to 90 but soon as you start driving it goes back down.

    Heaters do blow hot air so I am unsure if its the thermostat or the Coolant Temp Sensor. Can anyone help?

    Thanks

    If it is the thermostat, i can tell you it will cost about £40 - £50 as the thermostat on the 1.6 is map controlled and has an electrical connection. It is, however, very easy to change. Much easier than on the 1.8 engine.

    We should determine which type of engine you have before suggesting parts.

    A 2001 a3 1.6, I'm guessing it will be code AVU.



    Tom163: what is your engine code? It can be found on the first page of the handbook. I think it's the first three letters of the large code block.

    I wouldn't bother about temp sender, but if you want to you may as well do it when the coolant is drained down.

    as for the thermostat, remove the engine cover and you will see it at right hand side of the engine at the top. Remove two torx bolts, unclip the wiring and out it comes.
