Hey, I’m just having this to trouble with mine, engine management light & flashing glow plug light.
Had the exact same issue last September, guy who I have known a few years who does my MOTs had a look for me with the diagnostics machine, pointed to the DPF being blocked, despite the DPF light not actually being on the dash.
Neither active passive or manual regen would work.
The manual would start but then just stop after a few mins, being stumped He took it to another garage who he’d heard have dealt with this before.
He had it back from them the same day, all lights out, out of limp mode, he was told it was 89% clean. He didn’t get a receipt as I think they did it off the books a bit cheaper, I expect if I took it myself I’d have got a receipt but I’d have lace had to paid the full price, so I was happy for him to do it that way at the time, though didn’t have a detailed description of what was done or any guarantee. But light was off, van driving great , all good.
Anyway less than a year later same issue again. My mate came with diagnostic machine , won’t manually regen again & says blocked dpf. Admittedly I don’t use the van how it should be, I do regular shorter journeys & have a works vehicle & we have another car,so sometimes it’s not used through the week aside from a trip to local shop.
So maybe I can understand how it’s come to be blocked again, the thing I want to know though is why so little warning & why won’t it manually regen. The only time the DpF light came on was one evening when we was travelling home ,from somewhere local about 5 miles away, to give the baby his food & a bath, at which point it wasn’t an option to take it on the motorway to regen. Had planned on doing it the next day but when I started the morning after there was no warning light so thought I’d wait until the next time it came on. It never did & it’s blocked again now.
Sorry about the essay, I just would really like to know
1. How come the dpf light only came on that once briefly. (Surly for something as important as a blockage the dpf warning light should be ever present until it’s been regenerated)
2. Why it won’t regenerate manually.
3. Is it normal for it to block up again after 11 months.
4. Is it worth me buying a carista & try getting it to start regen whilst out on the motorway over 2k revs etc.
Thanks guys hope I’ve posted this in the right place, have read a few threads about oil pressure sensors & freyd cables etc also.
