Hi.
Just wondering if anyone can shed any light on what may be causing a DPF fault on a 2012 1.8 transit connect?
Read fault codes and got P2463 DPF soot accumulated (EML on), and P242F DPF filter restriction - ash accumulation (orange cog with exclamation mark in the middle dash light, and "engine malfunction" displayed on dash). Cleared fault codes and got the P2463 come up about 20 seconds later. Ran a regen through the diagnostics. It completed the regen (about 30 minutes) but the P2463 fault code still wouldn't clear. I have checked the connections and wiring at the exhaust gas temperature, and pressure sensor multiplugs, and all seems fine. I also get readings on live data from these. I've also removed the DPF and check the sensor pipes for blockages. The DPF itself didn't seem all that dirty (all the little holes in the cartridge were visable) but maybe it's impossible to tell by looking.
It wasn't until I had done all this and tried ereasing the fault code again that I noticed that it was clearing, then coming back up again about 20 seconds later without the engine running. Surely the engine whould have to be running to detect a proper blockage. This leads me to think that the sensor is at fault. Has anyone with more knowledge on DPF systems have any suggestions?
The P242F fault code only comes on after I drive the van for about 15 minutes. It then goes into limp mode.
