Ok altransit, I would concentrate on that intercooler as the culprit for now. i have a feelin we are close to solving this problem as i now think it was very similar to my own

Hello . I know this is a 14 old post and maybe nobody see this , but if you do , did you found what the problem was . I have a focus 1.8 tddi , the same simptoms as you did , and I have errors p0167 and p1564 on autocom . All this started 2 years aho when I changed the pump . I know it s an old car , but I use it to carry things arround , and rhe power lose bothers me .
It was getting harder to get an MOT with all the black smoke, and to cap it all, the airbag light wouldn't go out, also an MOT fail, so I reluctantly gave up with it.
It wasn't for the want of trying though
