Hi, tbh not fussed about having no dpf, but like your other a3 owner I've tried God knows how many cleaners etc. Will endeavour to find someone who can do the mapping.

Thanks

Hi sounds suspiciously like the DPF has been bored out and its had a remap as it definitely should not smoke as the DPF and CAT stop any excessive smoke, if it was standard you would have limp mode and codes.

Hi Steve, was my thoughts aswell tbh, just wish I could get the poxy light off lol. Guessing the only way to confirm would be take the dpf off and have a look. Thanks 

Hi All good evening.  Hoping for some pointers. Have recently purchased an 07 A4 2.0Tdi b7 135000 miles. Runs well, smooth, pull like a train great on fuel etc. DPF light has come on so have done the motorway run....twice added dpf cleaner to fuel etc and light went out.

25 miles later light came back on.

I may add absolutely no loss of power or limp mode etc. Quit a lot of.black smoke when you give it the beans.

No dtc codes 

Amy pointers on what may be the issue,

Thanksn
