outside temp sensor

[DublinChris]

So here is another question!!

Last week the display in the car - series2 Xantia 1.9TD - started doing strange things it initially hit up to 28 degrees then dropped a bit but back up again - think it reached near 40 degrees at one point - well now it seems to have settled back down - what could the issue be?

I was not travelling in Morocco or anywhere like it - just around Dublin where temp was in mid teens max

Thermistor failure.
They are generally located on the underside of the passenger door mirror, a little 'wart' at the bottom.
Fairly cheap to replace, about £13 at the dealer here.

You might also find that you don't need to take the wing mirror off to replace it. On my last Xantia there was a small 'hatch' by the sensor dome.

That's great thank you for that information will follow it up.

Thanks for this!

Kept meaning to look into this as mine consistently reads about 10C higher than the actual temperature. Will have a look into the thermistor.

Got quite a few random ones in the parts box...Will see if I have one that might do the job now I know where it is.
