    Has anyone on here had a problem with the ERG valve. Our son in law has just had a big problem with his and had to be taken to a local garage. Lucky the garage was owned by a friend, when they investigated it turned out to be the ERG valve. They decided between them to blank off the valve and now find out that the vehicle runs better and has been said that the MPG will improve. Any comments.

    It needs to be repaired or replaced. It will fail an MOT on exhaust emissions.

    Depends on the make and model, some engines will return better MPG with the valve blocked off and still pass emissions test IF it has an ECU that can adapt. Even if it has an ECU that can adapt then it will need some decent miles done to let the ECU learn. If its new enough then it should be fine, costs nothing to find out with the free emissions tests that are available in supermarket car parks these days.

    I run a Movano for work and it has had two replacements fitted. Not sure why they fail and cause a problem. It shows up by way of the engine management light illuminating and putting itself in limp mode. Could not believe it when the diagnostics showed it a second time.

    We had a problem with one on a 2007 Ducato 2.3 - when first starting sometimes it would appear to be in limp mode with no light on and sometimes the light came on but the engine ran fine. We had it replaced by the dealer (even though it wasnt covered under the warranty )

    I think what you fella's are referring to is an EGR valve, Exhaust Gas Recirculating valve, it becomes clogged up with soot when the vehicle is used for a lot of short journeys or when the engine is not put under load and revved enough, I had a Nissan Xtrail DCI that used to regularly clog up, I cleaned it out occasionally to cure low speed snatch insets when running lightly, was always OK afterwards for a while.
    Being an ex mechanic and MOT tester, one piece of advice I would pass on is to go into Wilco's if you have one near you and buy a bottle of Diesel Magic, it's in a red plastic bottle with a long neck, when your fuel tank is low, quarter tank or less, add the DM to the tank and take it for a good hard run, it will clean out the system and we almost always managed to get reluctant vans through the test afterwards, do not buy any other brand of additive and expect the same results, I do not have any experience with all of them, but I know Diesel Magic works, especially on older Diesel engines.

    On the recommendation of a mechanic at work, we blanked the EGR valve off on my 06 Volvo V50 when we bought it second hand with 30k on the clock. Speedo shows 137 k now and it‘s passed all it‘s Mot‘s. Didn‘t know about the “ learning” ECU thing, but in my mind, it ruled out one more thing to break down.

    A mechanic friend said to us , because you drive gently trying to get the most mpg it does not get hot enough to burn the recycled crap off. The best thing he said was once the van is warmed up when leaving the roundabout floor it. We did this and it's amazing how much crap comes out of the exhaust. :thumb:

    My EGR stopped working in Morocco and we lost a lot of power ,:Sad:

    The engine eventually died on us going up a steep hill " 2500 m ASL" , very serious as we had to reverse down hill , until we got to a flat bit of road to turn round , this was on a very sharp blind bend :Eeek:,

    We tried the " cut a blank from a coke can trick " :ROFLMAO: but it did not work .:Doh:

    EGR cost £395 fitted ... :Cool: No more problems engine runs better then ever ,

    blanked/deleted EGR valve should throw up a fault code and may even go into limp mode.

    You should see the crap that comes out of mine when I floor it :roflmto:


    And am I really clearing it out and improving things ? I do tend to drive steady for MPG.

    The new egr valve was about £138 , so if you spread that over the lower mpg it helps even it out. As said ,you can blank it off all together. We still put in millers additive every 2 or 3 tank fills of diesel to help it out.

    As has been said in previous posts, the main problem is that most owners drive their vans too gently. Occaisionally you need to drive it like you stole it, to avoid the build up of carbon deposits.
    We had a big problem with ours at the end of last year and was advised by a Citroen main dealer to replace the erg valve, 400€ plus labour.
    We ended up getting a product via ebay, called 'Forte' it worked a treat.

    Also, we have found that many things can cause the engine management light to come on and put the van into limp mode.
    We had a problem with plug for our gps was shorting and blowing a fuse, this also put the van into limp mode.
    I ended up buy a bit of kit that can erase the code and put the van back to normal running.
    On our recent 8 week trip through France, Spain and Morocco we used it a couple of times to help other owners sort their vans out. It has been the best 18€ I've spent in a long time
