I have a Citroen Xsara Picasso 1.6 HDi (2006), which I have had since new. It has done around 70,000 miles. Yesterday morning, when I started it, the Engine Fault light stayed on, and there was an "Engine Fault" text comment on the dashboard, with a "beep beep" audio warning. It was the same the two next times I started it, but the next time, the light went out when the car was started. Each time the light came on, it stayed on till the car was switched off. I was in a 30MPH speed limit, so I didn't have much opportunity to see if it was performing normally, but everything seemed OK - I didn't notice any difference at all.
The light did not come on while the car was in use - it happened instantly on starting the engine, so I thought it would be unlikely to be due to sensing a bad mixture, as that would take a second or two (I'm surmising here - if I knew the answer, I wouldn't be asking the question)
Does this herald problems in my near future? Has anybody had, and solved this 'symptom' (it's not actually a problem yet)?
