Hi
I have a Xantia 1.9TD LX 1996 for my sins. Driving home yesterday I had a fault which did occur a few months ago but only reappeared yeterday. The symptom is the engine stop light comes on together with the orange warning light at the top of the temperature gauge. Last time this happened the fans came on as well but this time the fault had vanished by the time I pulled up. Water level is fine, the engine is not over-heating, hydraulic level is fine. The last time this occured someone (could have been on usenet, could have been my local garage) suggested the thermostat, I have changed that and it all seems ok. The only thing other relevant thing I can think of is that yesterday I was using the aircon to demist the windows.
The fault didn't reoccur this morning of course.
TIA
