    Icon8 C5 2.2 HDI Engine management System Fault

    Well I guess it had to happen at some time.

    Started with the ASR failur / fault and loss of power.

    Currently getting Engine Management System fault, but do not appear to have any further loss of power.

    Located Lake Macquarie, so should I get a Lexia 3 or find somewhere local who can scan the codes and tell me what is wrong?

    I'd start with a load test on the battery. If your testing CCA are well down on battery's rating, replace that first.

    I think the NRMA can scan codes, but not necessarily interpret them well. So could many mechanics with generic scan tools.

    Battery is a good idea. Brake switches are another weak area and operating the pedal repeatedly might give you a temporary reprieve. Fuel quality/blackage? Also look for fuel entering the engine harness at the filter connector and see if it's present at the engine ECU and fusebox/slave unit. If there is fuel present, try cleaning it as a first step.

    Thanks for that info. I had read somewhere that they do like a string battery, so will check that tomorrow.

    Ok, so not really knowing too much about the anatomy of these things, coming from a Patrol background is there some diagram / info anywhere that can point me to all of the relevant bits that you mention?

    Thanks guys for the help

    Pull the covers off. You need to pull the centre plug out of the clips for the covers to be able to remove them or they break.
    The fuel filter is mounted on the front of the engine and has a connector on top. If it's wet, then look for fuel at other items connected to the engine harness. If it's dry, you can probably cross that possible fault off the list. The electricals are at the left side. If in doubt, take it to someone compentent.

    This happened to the '07 car I had....2.2HDI with sat nav, hard drive and everything you could get as a special factory order. Bought it from the Citroen dealer in Brisbane and it had been traded on a new one.
    From time to time it just went into 'limp' mode, and the engine management fault light came on. Stopped the car, waited a minute or two (no more) started it and away it went no problem and the warning light stayed out. Similar thing happened with the cruise control...periodically refused to operate and warning light came on.
    I took the car back to the dealer several times. Also took it to a local Citroen specialist and they both checked everything on a number of occasions and couldn't find out why. Even had the fuel tank drained, flushed and system cleaned. Checked electrical everywhere. couldn't get fault codes other than 'unspecified engine management fault'.
    After a year I had decided that enough was enough. Regretfully Traded it.
    I hope you find the problem. but i seem to recall a fellow frogger who lives in Mt Barker near Adelaide reporting something similar?

    David, I think this may have rectified the issue at least for now. Started the car and again got the error message. Pumped the brake pedal numerous times, stopped the car and restarted and sure enough the error did not reappear and is also gone from the trip computer history.

    Next question I guess is where do I source a new brake switch and what is the process for changing the old out for the new?

    Thanks for the advice.

    Hey Bigkev

    Pity that you could not get to the bottom of it as they are a very nice car to drive. Like anything if you have issues you begin to get extremely frustrated. You don't have to tell me about it. Way back in my young and stupid days I had an XJ6 Jaguar. Beautiful car to drive, when it was running. Unfortunately it spent most of it's time in the workshop emptying my wallet, so I know how you feel.

    The brake switch is probably now listed as a kit of a switch and harness, but you should check the parts system against your VIN. I think just the switch 453463 may work, although you may want the short extension harness too. Citroen and Pug dealers will have them, but eBay is another source. The switch will have a telescopic plunger on it and it whould adjust to the right length when you fit the new switch.

    SNAP! I always said that one day I would own a white Jag with red leather upholstery, like the 'rich people' drove.
    Finally, I got enough money together and bought a white XJ6 with red leather upholstery. Man, I was the business! I can't remember the year, (I think about 82 or 3) but it cost $32,000 which was a lot of dough back then......
    two years later I had spent just on $11,000 - yes, you heard right $11,000 on repairs and the bloody thing still wasn't right. Used to spray a mist of petrol out of the injector hoses which had little 'radiator' clamps on them. Fix one, star it up and another one would.......started it one day and there was a hell of a bang, huge cloud of smoke and a spray of oil 20 feet long out of each exhaust pipe. Full engine recon needed.
    Wonderful when it went, but ohhhh.......
    I might act like an idiot, and I might look like an idiot, but don't let that fool you: I really AM an idiot!
