    Every now and then I have a period that I get this warning, including
    flashing 'STOP' sign and a beep.
    The temperature meter reads normal values, I keep driving and no problems so
    far (except the beep etc.).
    This evening I had it for about half an hour (intermittent).

    Any idea what may cause this?
    Maybe a sensor? If so, where can I find it?

    Have you got air conditioning? If so it could be the Bitron sensor on
    the thermostat housing. Try taking off the connector cleaning and

  4. The stop indicator is also used for faults with the ABS system

  5. STOP sign also illuminates when brake or steering fluid are low. Tends to
    come on intermittently as level starts to drop.

    On a 306 with aircon cleaning connectors helped recently, this was for
    an intermittent, flickering light.

    Thanks, great site!
    I hope this is the answer:
    I'll check the resistor.

    Everybody else thanks, too, for your tips. If the resistor is not causing
    the trouble I'll try the other tips&hints.
    I'll post the outcome.

    It's terrible isn't it? You write perfect English and probably (like the
    other Dutch people I know) speak it too, yet I can't understand a word of
    your language. I'm sure that's a great website but I can't read it.

    I'm sure there must a British equivalent of www.problemcar.nl

    Try checking ur radiator fans if they operate v.well. Faulty relay within the fan unit could be culprit.

    My 406 D9 2004 had similar issue.The coolant temp gauge however was dropping to coldest and the STOP flash and engine coolant temp high warning would appear. How ironic. The fans would as well engage. Today l cleaned the bitron sensor connector, I believe, one on the radiator bottom right hand side. I also cleaned the three fan relays and connectors tucked inside a box on the left hand side of the single fan. Took her for a test drive and she behaved ok.
