    Question 1999 A6 1.8T Coolant Temp Gauge Problem

    Hi Guys, just after a little help here.

    When i turn on my ignition the temp guage picks up a reading, but as i drive it drops down to 60 degrees as though it is not working?
    I have also noticed that the oil temp gauge doesn't move either.

    Today i changed the coolant temp sensor but the problem is still there. I can keep my foot on the accellerator and the gauge will go up to 80+ degrees, but once i release the accellerator it will return to 60 degrees?

    I have bought a thermostat but havn't got round to fitting it yet. Do you think this may fix the problem, or could it be electrical?

    Any help appreciated.

    Thanks
