Did it fix permanently?

Et voila!fault cleared and engine running smoothly! No flat spots or lumpy bits since. Famous last words

I understand that its been over two years since you've posted your last update. I have the same problem on my 56 plate (2006 year) Ford Focus TDCi and I did see the same post you've mentioned. I did try wiggling, but apparently I must be not doing it right. The fault did come back after clearing, but doesn't go away.

The DPFE sensor was a bit loose on one side, so I tried to fix it properly (by simply nailing it in on the side it was loose) and did juggle the two pipes on the bottom such that they have some slack. None of it ever cleared the fault for me. I had to manually clear it, which would comeback within a week or so (sometimes even quicker).

If you are still subscribed to this thread, could you please post exactly what you've done (if you remember), but more importantly did the fix work permanently as it been 2 years now?
