Hi Gizzad - did you get your Audi problem sorted?
I have an A3 - similar experience - had the DPF removed - remapped and tuned - initial great performance but after 3 weeks and 400 miles DPF light on again, white blue smoke and engine into limp mode - had it remapped AGAIN and new sensor fitted but same problems after another 2 weeks - have you got yours sorted yet and / or any advice - greatly appreciated.
