    If its the thermostat, the gauge will rise if the cars left idling.

    To test it, drive around for 10mins or so, then park up and leave the engine running for 5 mins. If the gauge comes up the stats gone, if it doesnt its probably the temp sensor.

    Looks like it's the temp sender, where is it on the AEB engine

    the dash temp gauge is for the water temp not the oil

    Hmm ETKA is a bit vague.

    Its either 058919501A (black) or 059919501 (blue)

    It suggests the black one is used upto the end of chassis code T, then the blue one is used from V onwards.

    Murdoch: as i said above, have a drive to get some heat into it then leave it idling for 5-10mins and see if the temp comes up to 90.

    If it does, its the stat.

    Mine had similar symptoms. Changed the temp sender and it was fine.

    Also changed the thermostat, just to make sure!

    sounds like it could be the sensor then. Do you have climate control?

    If so, press and hold recirc, and press the up arrow, the display will change to 1c, use temp +/- to change it to read 49c then press recirc again.

    The display will then change to show the real coolant temp. See what that shows?

    had a go with the climate thingy, and it read the same as the gauge, never went above 62c, is that a new sender or thermostat?

    did it sensibly climb up to 62 though?

    Ie start at 10-15c then climb steadily?

    Also, switch the AC off when testing, as with the AC on it runs the radiator fan all the time, and this will further reduce the temperature if the stat is stuck open.

    I don't know, because I only got a chance to set it up at some roadworks, by which time it was up to 62c.Thanks, I will try that tomorrow, and have the ac off too!!

    Yes, the temp climbed steady to 65c, then fluctuated between 62-57c with all heating etc off, I lifted the bonnet whilst it was idling at the end of the journey, and noticed the fan was continuously on, is that normal?
    Skinz, sorry to jump on your thread, i thought it would be a good idea to keep it all in one, as it's effectively the same problem.
    Aragorn, thanks for helping !

    Which fan?

    There are two. One large fan bolted to the engine and driven by the aux belt, and a smaller electric one.

    The big fan runs all the time, but has a viscous coupling and should only run slowly with the car at normal temperatures. The small electric fan should only run when the coolant temp is over 95c or when the AC is on.

    It does sound like the thermostat, especially if the bits where it dropped lower than 65 where high speed low load, like crusing on the motorway. Its odd that it wont climb when idling, but i guess if the stat was really jammed open the fan may well be drawing enough air thru the rad to keep the temperature from climbing any higher.

    The one last check you could do, would be to use vagcom to compare the ECU temp reading with the instruments, if they're the same its almost certainly the 'stat.

    My temp gauge is not working
    audi a4 b6 1.9tdi 130bhp

    i have hooked a diagnostic computer up and done a gauge test on it and all gauges move accept the temperature gauge during testing.

    anyone any suggestions or advice

    much appreciated

    Either a new cluster or find someone who can repair it.

    This is the B5 subforum, your likely to find better model specific info in the B6 section if thats what you have.
