Xantia Temperature warning light

Post by xantiav6 »

Today the temperature warning light (and STOP light) on my Xantia V6 started coming on.
It came on about 5 times, for periods of 10s to 30s, during a 50 miles trip.
The temperature guage was steady at 70, and the fans were running at half speed with the A/C on. Turning the A/C off did not make the warning light go off.
When the engine cooled, I checked the water level, and it took 500ml to bring it up to the level I normally fill it (last checked a couple of months ago), but even after refilling, the lamp came on a couple of times.
So what can cause this?
Faulty sensor (which one(s)?)
The dreaded Bitron box (where is it on a V6?)

When my V6 did this it was the sensor at fault. (brown one)

Normally the STOP Light and the flashing temp warning light appear when the fans do not work properly. There should be 3 relais somewhere between the 2 fans that control the low/high speed of the fans. These are often the cause for problems like this. If the V6 has a BITRON box (I must admit that I don't really know), it should be under the left headlight.

it may be that the coolant sensor needs replacing as your fans are still working. It's easiest just to get Citroen to check the fault log on your engine management computer, and then get them to reset it.
