    DPF light on every 2 weeks

    Got the car booked in for DPF gutting and stage 1 remap on Monday. He said they recommend leaving the EGR valve as is to regulate the exhaust gas temperature. To prevent overheating of the engine. Does that sound right? I thought as part of DPF gutting you'd also need to switch the EGR off? He...

    DPF light on every 2 weeks

    I've just had it in with a Diesel specialist garage and they've run tests on the sensors and plugged it in to VAGCOM. No evidence of split hoses/pipes and everything looks ok. The ash level is showing as 0.00 and he reckons a previous owner has manually reset that because the DPF looks to be...

    DPF light on every 2 weeks

    So essentially you are of the opinion that it would be worthwhile to have the DPF gutted and ECU remapped? Would the EGR also need blanking off?

    DPF light on every 2 weeks

    Are there any complications with the mot when gutting the dpf and remap? Has yours been ok? Thinking about getting it done. Cheers.

    DPF light on every 2 weeks

    The Soot mass currently shows 22.18 but the Oil Ash residue shows 0.00. The app shows 97% blockage. Surely it should regen based on the high Soot Mass reading? I'm not clear at what point the DPF light comes on but I'm expecting to see it again very shortly with that Soot reading! I am hoping...

    DPF light on every 2 weeks

    How often is your DPF light coming on? I'm getting mine come on every couple of weeks which is no more than a 100 miles for me. I've got it booked in with a Diesel specialist garage on Wednesday to test the DPF pressure and Exhaust temp sensors and also check everything else that is involved...

    DPF light on every 2 weeks

    I have just used the vag dpf app to take some readings of the dpf soot levels and I was very surprised to see the ash levels at 0.00. Does that seem a bit odd? Wondering if a previous owner has set it to 0 in vcds.

    DPF light on every 2 weeks

    Thanks. For now I have had an oil and filter change and had the glow plugs checked (they are working fine). So I'll see how it goes now that I know for a fact I have the right amount of oil in it and it's also the C3 low ash low saps stuff. It might make a difference but I'm not really expecting...

    DPF light on every 2 weeks

    So I got a mobile mechanic to read the codes but it just said 'malfunction' next to the engine control system line. He said the engine management light probably came on due to the dpf issues I've been having so he proceeded to clear the codes without me knowing the reason for the EML being...

    DPF light on every 2 weeks

    Thanks. Just been out in it and it's not in limp mode anymore. But the dpf light came on again! That's 2 weeks to the day and I've only covered about 50/60 miles in that time! Took it on an A road in 4th gear and the dpf light cleared within about 5 minutes. But the emission control system light...

    DPF light on every 2 weeks

    Do you know of any members with vcds that could do a code read in the exeter, Devon area? Hoping it's a sensor and not the dpf itself! Although if it was I would expect the dpf light to be on.

    DPF light on every 2 weeks

    Update: just been out and there was no dpf light but the glow plug light is flashing and the emissions light is constantly on. Both amber. This hasn't happened before. Feels like turbo has gone as I've got a big loss of power. Am I in limp mode? Could a sensor have failed or something? Or egr...

    DPF light on every 2 weeks

    What sort of cost am I looking at to gut the DPF and remap? Not sure if there's anyone around here (Exeter, Devon) that does it.

    DPF light on every 2 weeks

    Ok thanks for your suggestion I'll get that looked at also. What about the incorrect oil? Could that cause the DPF to clog far quicker? I haven't changed the oil since I got the car in October so I don't know what the previous owner has put in it. I just assumed it would be ok as it was serviced...

    DPF light about every 2 weeks

    Hi, Old thread I know but did you manage to get to the bottom of these DPF issues? I have exactly the same issue. DPF light illuminating every 2 weeks.

    DPF light on every 2 weeks

    I have no idea if the EGR could have been mapped out. I would have thought the fault code reading diagnostics would have flagged something EGR related if so?

    DPF light on every 2 weeks

    Thanks all. I've just been to a Bosch service centre who specialise in Diesels and they've offered to test the sensors and diagnose the issue. £72 +vat just to diagnose though which sounds quite high to me. They said the would normally come on every 300-400 miles or so but I'm not getting near...

    DPF light on every 2 weeks

    Ok thanks. I'll see if I can get a garage to test the sensors as a next port of call. When your friend had his cleaned, was that a proper clean with the DPF taken out or a clean with fluids with the DPF still in, like a Terraclean type service? All of the DPF clean services around here (Exeter...

    DPF light on every 2 weeks

    Wouldn't a dodgy sensor have shown up as a fault code on the diagnostics machine? Hoping the DPF isn't at its end of life! Understand they aren't cheap at all!
