Do these even have a DPFE fitted? The only mention of them in this site is these threads. Google search mainly comes back with Fords and VAGS having these.
Never heard of it myself plus thats what i found also .Ford focus seems to have this problem also all i could find are vids on youtube testing the voltage to the egr but i haven't had the chance yet been too busy. I changed the egr as i had a spare at the garage but spanner light still been on a couple of times since. cleaned the egr pipe airline through it , a bit of soot came out but nothing major that would cause blockage nothing in the block either poked a welding rod straight through so will try and get the voltage tested see what happens. If i cant find out anymore info then will probably try the egr cheater
