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

My DPF light as come on 3 times in the last 4 weeks, the first two times it just went off but it as just come on again and doesn’t seem to be going off.

Just recently installed a neuspeed intake in my 2012 A3 8p and about after 3 weeks i was driving on the thru-way and my engine light popped on. The codes read for a p2002 Particulate trap efficiency below threshold bank 1 *permanent* - Pending - Confirmed. 3 codes in total. Car has never been in limp mode and drives all the same. Any idea if the intake could of caused this? Or is it just bad timing. Anyway im having audi take a look at it but it should be covered if it needs to be replaced because of the whole dieselgate thing. If anyone could give me insight would be a huge help.

I have a 64 plate 1.6 tdi and the engine management light has been on since I bought the car in Feb 2019. The error code comes up as dpf but I have had it done countless times and the light still come back on. On my last attempt at Halfords, they said the engine rumble/ vibrates at 4k revs. Anyone knows what could be the issue. It drives perfect and pulls like there is no issue

Hello everyone. I am new to this forum and i hope i can share some valuable information and prevent a fellow Audi owner from spending a fortune for no reason. I have a 2008 Audi A5 3.0 TDI Quattro. Recently my DPF warning light began to come on and it only got more and more regular and i found that i had to take it for a blip down the motorway every other day. As you can imagine, eventually the dreaded glow plug warning light started to flash and it put itself in limp mode... I knew that now my dpf filter was so clogged up that it was surely a replacement job which i have been made aware can cost over £1,000 in bills. However, following some research i found a DPF cleaning specialist who use the very popular Terraclean equipment and were mobile. He ran some diagnostics and found my DPF had nearly 60g of soot and the pressure was between 10 and 13psi! =O. For those of you who do not know, the dpf pressure should not be more than around 3psi upon hard acceleration. The specialists words were "yep, it is f****d". He was not phased and got to work immediately. He connected his machine and all the pipes, set up the chemical they use and began blasting it through the dpf system. After 30 minutes a ghastly cloud of smoke and some grimy bubbles came out of the exhaust and the process had finished. At the end he reconnected his diagnostic equipment and the dpf was now reading 15g of soot and between 1 and 2.5psi upon acceleration, pretty much good as new. This entire process including him coming to my home cost only £250 and my Audi has never ran so beautifully! My word of wisdom here would be; do not run straight to the main dealer for DPF issues as they will simply charge you £1,500 to replace it just for the same issue to occur in another 30,000 miles. Find your local dpf cleaning specialist and have them clean it for you. It takes maximum 1 hour and will save you a fortune. Hope this is of some use to people =].
