    Temperature display inaccurate.

    2003 2.0dti
    The temperature display is reading 2 degrees too low and on trying new probe is still the same.
    Is it possible to adjust the displayed temperature in any way to bring it closer to true temp?

    I don;t know of any way to adjust it. Where the connectors clean on the outside as a bit of corrosion could cause resistance that may give a false reading

    What are you comparing it against? How accurate is your "other" method of measuring the temp

    Providing the ambient sensor is clean and both your methods of measuring are conducted in the same position then maybe another display unit is called for.......but why just for the sake of 2degrees is a mystery to me.

    Indeed its not really designed to be super accurate.

    Got out of my car (-0.5) at work this morning and into my van which was -3.0. They were parked right next to each other, only the car had just had a 15min drive and the van hadn't been started up.

    The temp sensor is never going to be very accurate. Which begs the question which was more accurate, the van which hadn't moved for 16 hours, or the car which had just been driven?
    In the summer, i'm sure a parked black car would think it is a much hotter day than a parked white car
