I sent in your direction [you are crd] a 1600 focus taxi on fri with a very long story.
I normally believe in keeping dpf's on and repairing. This was taken out of my hands on this occasion.
The car came to me on 60,000 miles from a mobile mechanic for a refill of the fluid and reset. About a month later it came back with a dpf soot overload fault. So i did a static regen, which it did successfully. If he were to come back he would have the option of a new dpf or a clean out with tunap which has reported success on this forum.
He came back about a month later saying the mobile mechanic had taken it somewhere and had the dpf removed and could i just reset the dpf[which i did expecting low pressure faults] The light was still on reporting high soot content. So i tried a static regen. Which to my surprise worked.
I put it down to the software[60,000 miles seems to be a common mileage on these focus,s] having to see a regen before it will clear the faults.
A happy taxi driver for 60,000 miles [again to my surprise]
The car came back with the same codes of p242f-e1 p2458-21 p2458-61 which are related to regen and and soot overload.
He told me the car had just had its second turbo from ECP which caused me to advise him of a poss oil pressure problem known to these engines.
I checked the pressure in the dpf and they weren't to high. So thinking the dpf wasn't getting hot enough to regen on its own and the software wanting to see a regen to reset the light the owner agreed to a static regen knowing of the poss oil pressure problem.
The oil light came on just as the regen finished.
The owner was there watching. Another long story later. I will not do a static regen or try to buy a secondhand engine for one of these.[there aren't any good ones out there]
I have now heard of two more of these engines going wrong on a static regen.
Approx 1,000 miles later the car came back on thur with the same dpf codes. I cleared the codes and went on a road test with the owner driving. We went once around the m60 and the dpf regen'ed twice and the temp went to about 600c when regening. The pressure started of cruising at about 12kpa and under load 15kpa and when we finished it was down to 7kpa cruising and 10kpa under load. There were no problems driving. One code returned p2458-61 i think.
The next day he returned back in limp. I wasn't going to do a static regen so i sent him to you at crd.
I told him not to just have the remap done but to also have the dpf opened up and what is in there to keep the light out for 60,000 miles removed.
This is a poss reason for why you see a lot of dpf removed but a remap not preformed. I asked the mobile mechanic where he had the dpf removed. He had to take the dpf of and take it to a workshop in Farnworth who cuts them open and re welds. He hasn't got any software but he claims not to have any problems with them afterwords.
They probably all end up at your place.
I did try to fix a A4 after he had removed the dpf but had to give up and send him of for a remap. Sorry for the very long post.
Regards Ian.
p.s I now believe he doesn't remove all the brick but may be 2 thirds.
