Hi, probably should have added more info, but in truth the question as I've asked it above is what I really need to know.

Have a Transit I'm looking at 2011 2.2 fwd that the turbo has seized and it's broken down up the road, I'm pretty sure that the DPF is blocked with what I assumed is turbo debris/oil. I can remove the 02 sensor from the front pipe pre DPF (It's a Euro5) and the van will run as I'm venting the exhaust, but with the 02 sensor in place, the van struggles to start, won't rev etc. (Bearing in mind the turbo has seized, I know it won't run properly etc etc)

I was told previously by Ford technical that the soot accumulation figures in IDS datalogger aren't very accurate.

For future info I'd like to know what voltages should be seen at the differential pressure sensor to prove how blocked or not a DPF is.
