Hi Sg here have found answers my 3.0 tdi b7 ASB 2008 has a built code 7NG and does not have a dpf does have a cat straight off turbo with pre oxygen sensor and post exhaust gas temperature sensor also another temperature sensor pre turbo has a secondary cat under car so because no DPF doesn’t have exhaust pressure sensors.

Thanks for answering Steve still not sure found some answers on other forums saying the opposite and the code if you had one was 7GG have just had the car scanned because it had always black smoked on hard acceleration he did a live scan found nothing relating to fueling or emissions strangely he said the soot percentages were 0 made me wonder about the exhaust pressure sensor have never been able to find pipes coming off what I thought was the dpf but it wouldn’t have one would it ? if it didn’t have a dpf going to try Audi surely they will know for definite.

Hi guys need to know if I have a DPF fitted on my A4 B7 3.0tdi Quattro have found this PR code 7GN on the production sticker in service book which I googled and got the answer PRcode 7GN=emission standard EU4 DPF preparation does this mean I have or do not have a DPF?Thanks. Sg.

Hi Steve Q thanks for reply sadly mine isn’t there, it is on the same engine as mine in the A6 but mine is A4 3.0 tdi some A4’s where the dpf is underneath the car it’s near in the transmission tunnel my dpf is straight off the turbo tight in the back of the engine I think like yours but that’s where the similarity ends don’t think it’s in the top of engine bay l suspect it’s down the side buried towards the back near where the DPF pipe goes down, the back sensor must be on the pipe down there was hoping someone knew exactly so when I was scrambling around underneath I could go straight to it. Thanks again Sg.
