Code P2279-11 - EGR Valve needs a clean?

    Recently got limp mode followed by EML light coming on :grrr. Vectra-C 1.9CDTI Z19DTH.

    Bought an op-com off ebay and it gave me a fault code of P2279-11 although there was no text to say what it meant.

    Reading other posts suggest this could be something to do with the EGR valve or possibly other components of the air intake.

    I'm looking for advice on whether I should try cleaning the EGR first and see whether that fixes it, or whether there is something better to try first.

    Any ideas appreciated.

    Took the EGR valve off anyway. When I took the 4 torx screws out and separated it I found that the solenoid plunger was stuck. I drilled a hole in the plastic at the end and tried to get the solenoid mechanism out to clean it. Despite several decent whacks with a hammer it wouldn't budge so I sprayed WD40 through the hole I'd drilled and then pushed the solenoid plunger in and out for about 10 mins. This really freed it up nicely. Put it back on the car and the problem was fixed! A main dealer quoted me £104 for a new EGR value (part only) and they said they were on back order due to high demand. They also had no gaskets in stock again due to high demand. I took a risk taking it off without the gaskets but managed to seal it all up fine with the old gaskets, even with one of the four manifold bolts missing. Someone must have obviously been at it before and lost a bolt when the car was with it's previous owner.

    If it jams again I may be able to get away with just spraying some more WD40 in the hole I drilled and prodding it with a screwdriver for a bit, without even removing it from the car.

    DIY is definitely the way to go with these EGR valves if your car is out of warranty to save a load of cash.

    Given that the part is a hefty £104 new from a dealer they should have made them better and more reliable in the first place.

    I bought an 06 Vectra 1.9 CDTI with less than 35000 miles 6 months ago, which now has an intermittent fault, its this P2279 fault code which I have been advised could be a multitude of things. I hope someone can help!
    It has developed an acceleration problem whilst at low RPM, generally around 2000 RPM it is terribly sluggish. This only happens occasionally but i think it is when the engine is overloaded. But when this does happen, the Fault light doesn’t always come on. So not only is the problem intermittent but the fault light is intermittent when the problem occurs. As soon as the RPM reaches 3000 the car kicks back in.
    The fact its intermittent leads to think it’s not a permanent fault (Solenoid stuck, or blocked pipe) I have had a garage check the pipes which have ‘No signs of leak’ I have had the EGR valve inspected and cleaned (little signs of carbon) and the MAP sensor inspected and cleaned (very carbonated). No change, this cost me £140 to not have fixed. But at least I got some information. Now Vauxhall want to charge me £75 Diagnostic charge to start all over again. I am wondering if anyone has any ideas as I really can’t afford £75 to be told what I already know.

    Hi and welcome to the forum,
    if i know the engine code i may be able to help you, but i have based it on an 06 plate 1.9 cdti with an engine code of z19DT if the fault code your getting is 2279 then the cause according to autodata is "intake air leak"
    cause "mechanical fault" but it dont say more than that.

    This is very common faullt but what do you expect from a FIAT engine.

    The inlet EGR valve cloggs up with carbon and 90% of the time just needs a good clean. Its about one and half hour job with most of the time spend cleaning it.

    The EGR is based at the back of the engine on the right handside next to the expansion tank.

    I thought 1.9 CDTi was Isuzu ? or is that the 1.7 ???

    This is what mines doing but its a 1.3cdti. i took the inlet manifold off and egr and cleaned them but its still the same. the inlet hole in the manifold wasn't even an inch wide due to the carbon build up. cleaned it all and its still the same.

    Ive seen on the forum that people have adjusted the EGR valve. How can you do that, there is nothing to adjust :S ??

    Not sure about the 1.7 but the 1.9 is the same Fiat Doblo used alot for Taxi wheel chair access. Repaird 3 Fiats and 2 vauxhalls all ready. Customers had been told by the main dealers they need new EGR valve then need reprogramming.

    Did you clean the EGR with a good cleaner so it dont stick? We use forte intake cleaner as it dont take the laquer of the parts. Some people have used brake cleaner but it cloggs up the EGR valve even quicker as the laquer comes off and the carbon sticks like sugar to a blamket.
