    Hi everyone,

    Ive just replaced my engine coolant temperature sensor (the one on the right hand side) of my Audi A3 Tdi (BKD engine)...as I had an irratic idle, dead temp gauge, engine light on and the fault code.... 16502 - Engine Coolant Temp Sensor (G62) Signal too high.

    After replacing that (made no difference to anything) the engine fans are constantly running, as soon as I turn the ignition on.

    The car was/is losing a small amount of water and i have to top up every few days.

    I only have a cheapo code reader and it won't erase any codes.

    Please can someone help with what this might mean and what to check?
