Has anyone had this problem?, i have 53 reg 2.0 hdi deisel xsara picasso, about four times now it has stopped with just `engine fault' on the dashboard, it will not re-start for about 20-30 minutes then it's sluggish. eventually it regains power and the fault light goes off.
any ideas what the fault could be?

wolfman - could be lots of things. Have you put any unusual fuel in it? Anything else out of the ordanry? Any other faults? When you 'engine fault' do you mean the MIL light? Try fuel filter.

Could be worth checking out the operation of your brake light switch, it may have an intermittent fault.

Sounds odd, I know, but if you do a search on this site you will see that this switch can cause all sorts of problems including power loss and engine cutting out.

Its possible but wont cause MIL light to come on.

Won't it...? <_< Are you 100% sure of that? <_<

I had a fuel pump failure and the display flashed up 'Immobiliser fault'. Where's the logic in that? :wacko:

Wolfman2 mentioned a loss of power, which has many times been associated with brake switch failure.

The brake switch is mapped to the ecu - it is meant to cut power.
If the switch it in the open position or the closed position neither of these are an 'error' i.e. the ECu will see them as both being valid.

However having a fuel pump (which pump do you refer to?) say the Hp one will cause a fault.

Yes - I am sure.

Sorry to post here, unable to create a new topic.

2 weeks ago I brought a 55 2.0 HDI. Today, I filled the tank up and added some redex fuel treatment...just trying to keep the injectors clean. 2 miles later on starting I see the message 'Engine Fault' and the light stays on constant.

Could the redex have caused a problem or triggered a sensor?

Thanks in advance for any help or advice that can be offered.

Incase anyone else has this problem, just found out it was the redex at fault. Do not put any additives into your fuel tank!

I have a 1.8 petrol,engine management light comes on sometimes when starting the car,sometimes while I'm driving,
but never goes off while I'm driving. I usually find it off when starting the car,after 3-4 days from being lite.
The car runs/starts as normal !!! I took it to the dealer who could'nt find any thing wrong but he switched it off from the diagnostic computer. 3 days later it went on again ...
WOULD A BATTERY DISCONNECTION SORT IT OUT ???
PLEASE HELP, ESPECIALLY MR CANYONDUST.

My 1.6 hdi (110) xp is a 54 reg. It has triggered off "engine fault" several times. Yesterday, it came off again on motor way. I was feeling the car was braking itself (often, especially when I drive around 57-62 miles/hour). I tried to give more gas, then the orange light on. Before, I restarted the engine several time, that light will go away. But this time it seems will stay there for a while. Have you got any idea about this? I think it may be a problem with the brake sensor or switches. I'll check it with a garage. I took it to citroen main dealer before. They updated my ecu program but does not help a lot.

I can only go by my experience, I had problems starting the car whilst hot and the EML on, it turned out that the oil level was low. Topped that up and haven't had a problem since.

just joined this site after experiencing the engine light fault !!!!!!
took it in for a diagnostic check and was told short circuit in coolant temp sensor wascausing the problem . Had no other symptoms or problms , car runs normally . just anoying seeing warning lights !!!!!!!

As TR above, I once had the "engine fault" message come up, and as I was away from home the first thing I could think to do was check and top up the oil (I have a very slight leak). The message didn't come back on again!

Hi just like to add my experience i was driving most of the day when suddenly the engine stopped the engine management light came on the car dropped speed to approx 50 mph then started again, light stayed on . the next day light was off and car no problem, few days later while on morway the same thing happens again next day the light stays on! local garage could find nothing major with computer diagnosis and suggested as a one of try some engine fuel injector cleaner this had the desired effect, but after a few hundred mile same thing again put some more cleaner in to fuel and hey presto no more engine cut outs so now put cleaner into the system whenever i think it nessesary, sorry for the long winded reply but there you have my experience!.

so in that case maybe its related to one of the lambda sensors just getting a bit fouled up.
