Diesel EGR fault

    I have a Diesel 1.6 yeti, the VW engine, which has started with the dreaded EGR fault code and going into limp mode. Checked the code myself (confirmed by garage) and it is "egr circuit malfunction". Tried all the DIY options, sprays etc. but these are just sticking plasters.

    Low mileage car car 55k on a 62 plate with the software "cheat" update. A garage has suggested what they call a "power clean" to see what happens at £40, they have a Forte machine. During lockdown it hasn't done many long trips, if any, which can't have helped. Anyone tried a carbon clean?

    Don't have any issues with getting the egr changed but it is labour intensive as it is at the rear bottom of the engine and all sorts of bits and pieces need to be removed to get at it, really need a lift. If it was sitting on top of the engine I would take it off myself and have a go at cleaning it. With labour close to £400 for a garage to put in a new one, which is fair enough.

    Irritating the location of this thing as I wouldn't think twice about taking it off myself and having a shot at cleaning it if it was in an accessible location; not really the money but the principle of the thing that gets me. These days everyone just seems to unbolt stuff and chuck it.

    Have you tried belting it alaong the motorway for half an hour in 4th/5th rather than top to get the engine/exhaust really really hot?

    Yes, no joy. Took it out today, the light was off, got it up to temperature, oil and water, and then the light came on and it went into limp mode. Couldn't get above 60 mph. Put a bottle of Wynns extreme in the tank beforehand.

    you can take the filter off and use a pressure washer to blast the crud out, that or as someone else said, blast it up the motorway, does it not have a regen function ?

    A pressure washer in the inlet manifold!! Already taken it up the motorway and no go I am afraid.

    It is abs EGR fault not DPF. In any event they are in the most stupid position and takes hours to remove.

    I had a look around the Skoda forums and there doesn’t seem to be an easy answer. EGR valves do clog and this one is he’s to get to.

    I wonder if it’s worth looking for and EGR emulator

    I am going to try the carbon clean at my garage, worth a punt to see what will happen. Definitely an EGR code on mine and the garage's OBD readers, mines just a cheapo. Don't hold out much hope, if not new egr. As you say, very difficult position which means around 4 or 5 hours to swap if everything goes well. I too have haunted the forums!!

    Really irritating because if I could get to it easily I would just have a go at cleaning it out myself.

    I had a Toyota with 2.3 diesel. They only way to fix the issue was to get the EGR valve out, easy on this model with just 4 nuts and an electrical connector, brush out as much carbon dust as possible, then carb cleaner and rags. Extremely messy ! It initially worked for 18 months, than became annual when I got rid of it..

    Just wish I could do the same. VW couldn't have put it in a more inaccessible place and this appears to be a common issue across the whole VW range that use the engine and its derivatives and with other companies who use their engine. One supposes that they must have had a technical reason to put a part which will need servicing\replacement at some point in such a place other than creating work for their franchisees. After searching around online there appears to be a thriving business in blanking plates to take the EGR out of the equation and to map it out of the management system; I am not going that route. I have had it six years and spent nothing on it other than the MOT so must remain philosophical.

    Will see how the "carbon clean" goes, don't hold out much hope, and then go for replacement if it makes no difference.

    Just to update this.

    Got a Forte carbon clean, took about 45 minutes and £45 or thereabouts. They hooked up a machine that they have invested in; not a hole in the wall outfit, haven't used them before but seem to know what they are on about. They say many of the local taxi companies use them for this.

    Anyway, it's cleared the engine fault lights, EGR fault codes and going into limp mode, and now seems to be running fine. Appreciate it is early days but worth a shot as changing the EGR is a bit of a job on these 1.6 engines, same engine as on many Skoda, VW\Audi cars. Quoted £450-500, more at a main dealer, most of that is labour. Will go that route if it comes back however.

    May well be a result of the many short trips made over the lock down excitement without a good long run to clear things out. We''ll see how it goes but it was worth a shot, I think, whatever.

    Good news. Let’s hope it is permanent fix.

    At £45 even if you have to go back after 12/18/24 months, it will be worth it . Nothing worse than a limp home mode, with people behind thinking you are being deliberately slow ! Worse, hope there are no hills on the way back !
