EGR valve clogged. Hope you didn't waste your money with the turbo, filter etc trying to clear that fault....

Pull the EGR off, clean with paraffin, replace, clear fault code, job done. 1 hour at most DIY.

hi

if you have problems with egr after replacing dpf all soot from the engine would go to the dpf straight away . That's why it propably clogged up dpf again. How much did it cost you to change dpf filter? Why you didn't decide to remove dpf completely?
