This Transit Connect 1.8 came in with 51134 miles on with the following codes:-

P2463 DPF soot accumulation
P244B DPF pressure too high

As it was quite easy to do the DPF was removed for off vehicle cleaning. It was refitted and DPF adaptions reset and a test drive all seemed ok.

Came back a few days later with the same issue. No other faults were aparent and vehicle drove fine. An aftermarket DPF was fitted but in less than 800 miles this had the same fault.

The Differential Pressure sensor was reading 30kpa at idle and then going upwards of 200 on reving. All the pressure sensor hoses/pipes were checked for leaks and blockages and even a spare sensor was put on as we're sure it couldn't have blocked up in the space of a few days use.

We have since cleaned the original DPF and put that back on. This time the pressure values are about 2-3kpa at idle and then on full load it goes up to about 180kpa.

What we would like to know is what are acceptable readings? If we send this out again is it going to fail?

We have tried to do a static regeneration using Ford IDS but it gets to the very end and says it has failed but no explanation! Also when looking at the live data for the back pressure IDS has no useful help information at all.

I guess our next step is to check if there are any updates for the PCM.

I suppose we could just do with finding out what back pressure values we should be seeing are and whether a new DPF could clog up in a few days given there is no apparent running issues with the vehicle? Or are we missing something else? We had thought of disconnecting the front of the DPF to see if there is any obvious excessive smoke going into the filter as the exhaust at the rear is clean.

P.S. Not sure on the engine code, is P9PA? Endura DI engine
