Evening all,
Having an issue with my 2018 2.0HDI Citroen Relay (88,000 miles) that I’m struggling to diagnose (leaving us stranded in Spain and requiring recovery) - since getting home no luck either.
I noticed for the first time DPF yellow regen light coming on from time to time (2-3 times for around 30 seconds or so over 1,000 miles or so) but thought not much of it thinking it was doing regens, never seen this before in the 10,000 miles or so I’ve driven the van.
Then out of the blue the light comes on and goes off after a few seconds several times in a 10 min period so the regen clearly is failing - I’m getting the text message to keep vehicle moving (was on the motorway at the time keeping the same speed and right revs etc). This led to the dreaded limp mode and check engine light,
After trying to force a couple of regens and a few engine on/off over the next day, I then got the check ad blue system error as well as the check engine message and light. The van was still trying to regen every time it got above 20MPH but failing.
A local Spanish garage plugged into their diagnostic system and no error codes other than too many failed regens. They forced a regen and then re-reviewed all codes and readings showing everything to be all good. Took it for a 15 min test drive and no problem. Tried to force another regen just in case but wasn’t needed
Got back on the motorway and within 30 miles, limp mode and check engine again (after the yellow DPF light came on for a couple of seconds with the keep vehicle moving message)
Fast forwarded 3 weeks whilst the van was recovered back to the UK and it’s now not in limp mode but the engine light still on, read the codes and now showing P2563 (Turbo boost position sensor). Cleared codes and was fine. Checked tanks are full and no visible damage to exhaust system underneath van either
200 miles later, limp mode and the same error code.
Does another have any ideas what the fault is and what the cure will be? Is this a DPF/emission exhaust system issue or further upstream?
Thanks for your help!
