Hi people. 2011 1.6 TDI A3 8P **I had a stage 1 remap and EGR delete done in 2020** Been having no end of problems with my DPF over the last month or so. It started about a couple months when my car went into limp mode after the DPF light had been on for a couple days - I got a technician to come out and force regen it to which the light disappeared and all was well until the light came back on a week later (with no fault code showing when scanned - odd). After driving round at high RPM it still wasn't budging, took it to the garage (went into limp mode on the way there) had the DPF chemically cleaned, engine temp sensor and DPF pressure sensor replaced to no avail as the light still shows and doesn't regenerate. It isn't blocked (yet) and all the parameters for regeneration are being reached but it just isn't doing so. Rang the place I had my remap done to see if it could be anything to do with the ECU but they said that won't be the case. I've booked in to have my ECU reverted back to factory settings to see if that will do anything but that won't be for another couple months so I'm trying not to drive it incase it goes into limp mode and causes more damage before then. I've been advised to have the DPF removed and remapped but I'd rather not unless it's the only option left, could anyone advise any other things I could try before doing this? Need to sort this out ASAP ideally as I have read continuous blockage/limp mode can damage the car even further. Any help would be majorly appreciated! Thanks in advance
Hello, I have 2.0 TDI audi c7. I have engine management light on. When i scan for error codes i get dpf bank 1 above threshold. Recently, i got my dpf cleaned, i was told by mechanic that it wasn't bad but still he carried out forced regen and everything. -no limp mode -regenerates every 200-250 miles -soot mass calculated/measurd below 25g. -45mpg combined mileage (not bad) But i have noticed that sometimes soot mass measured goes in negative value. And at idle my dpf sensor voltage is above 1V. I dnt understand why my engine management light is on because of dpf although my car is not in limp mode i have done about 1000+ miles with warning light on. Could someone plz help me to get rid of engine management light? Thanks.
