I tracked the regeneration of the DPF for approx 6 months via my Lexia, the regeneration procured every 600-700 miles and when the filter indicated it was 100% blocked and I have no problems with the car.

Long of it is. almost £300 for egr and £300 labour tidying wires along with free recall work. I was also told the DPF is gone, and warranty on EGR valve will not be honoured if DPF is not seen to. They said 120000 is good for a DPF. Did report plenty of fluid though, I do lots of motorway work so regeneration not an issue. xHUR.
