I can only provide you with official PSA part numbers as there are so many variations as the engine designs and Euro standards change.

I'm sure they will be able to check via your registration, but if you want us to provide official live part numbers and parts diagrams, we do ask for a membership upgrade as we are charged by PSA. This will cover you for up to 2 years of enquiries though. Details below if interested:

Hi again
Week before last I fitted the new dpf https://www.ebay.co.uk/itm/162849752485 ... nl%3Dmkcid then told the ecu that a new one had been fitted, and cleared all faults, however around 500 miles later - risk of clogging warning started to appear again, then around 600 miles engine management light on and no power, presumably - limp mode
Ran diagnostic and got the following errors
P2455 Measurement of the particle filter differential pressure - I believe I found the problems for P2455 as there was leak in dpf to turbo coupling (I hadnt seated it correctly when refitting it)
P1536 Measurement of break pedal position - Guessing here that this fault is connected to the wheel sensor fault?
P242F Particulate filter
P1490 Particulate filter
P11B2 Measurement of the EGR exchanger bypass positon - short circuit to positive
P14A4 EGR heat exchanger bypass - confirmed jammed shut (cold side)
U1213 Intersystems CAN
U1213 Intersystems CAN
Also:
C1330 Front right wheel speed sensor signal fault - this had recently been replaced however on inspection I found some sort of gunk wedged under sensor so hopefully this was the problem
I am guessing U1213 was a loose plug connection that sits at the top left side of the engine for the two pipes going to the dpf sensors?
As for the EGR and DPF faults Im stumped and would really appreciate some advice
I took the EGR off and it really doesnt look that bad.. just a bit of surface soot/carbon see pics
Any advice very much welcome

Your P2455 fault relates to the differential pressure sensor reading too high a voltage (higher than 4.7V for 500ms). If this is faulty, then it can make the engine ECU think the filter is blocked and hence the warnings (and the downgrade mode after 8 hours in this condition).

So that's where I would be looking first.

This plug is the one that had loose/broken connection.. plug goes in all the way but doesnt seem to lock in as it should, previous to replacing DPF this plug was not broken and this fault was not showing. I was only getting the 3 faults P14A4, P1490, P242F - so if I now secure the plug, I would hope it clears this fault
Also, on further inspection to the diagnostic, the fault - U1213 Intersystems CAN is coming from ABS, so Im hoping that by clearing the gunk under sensor it will remove this fault
Should I put back EGR and box everything else up, then clear faults to see if any faults come back? or should I be checking something else before doing this?
Any further advice very welcome!

If you have the EGR off at present whilst you've been cleaning it, this will trigger some engine management faults at some point if it is not reconnected. But the pressure sensor issue needs resolving as that will trigger other conditions of course.

Ok thanks for info Marc
If Im understanding correctly - I will put EGR back, box everying up, making sure the suspect plug is secured somehow and clear faults.. Then hope that no faults come back, just wasnt sure if before doing this I should be checking anything else?
