DPF and glow plug error codes linked?
trying to price up between fixing my current car or changing to a petrol car.
Current list of error codes are as follows: P0002 Status: Pending fault present, Validated and stored in non volatile memory, Validated fault present at time of request Fuel volume regulator control - circuit range/performance P0380 Status: Test is inhibited by other DTC, Validated and stored in non volatile memory, Validated fault present at time of request Glow plugs, circuit A - malfunction P2452 Status: Confirmed Diesel particulate filter (DPF) pressure sensor A - circuit malfunction P242F Status: Confirmed Diesel particulate filter (DPF) - blockage/ash accumulation My understanding of these is firstly needs a new DPF, its the original unit, cars on 120k miles and has had this error since the day I got it from my grandparents 6 months ago. As you can imagine they just pottered about so it never got a chance to clear and despite my best efforts it wont regen enough to clear the faults. Once the dpf is changed is it also going to start needing more work i.e. glow plugs sound likely, in which case id be more tempted to switch it for a petrol car. |

Glow plugs aren't so expensive to replace.
You didn't write what engine is in the S40, nor from when it's from, but if it is a 1.6D or 2.0D, the DPF should've been replaced at 75K miles and probably needs refilling of the Eolys additive by now also, possibly along with a new pressure sensor. In my experience there are less issues with a petrol car, especially if you don't need to commute long (motorway) distances daily. |

My bad, it’s a 2.0d from 05
It had its additive tank replaced earlier this year and refilled. Most of my driving is 10mins to shops and back then an occasional drive into the Peak District from Sheffield and a drive home from university about 5hr journey. Back home I’ve been doing domino’s delivery driving which is not great for it but still better than what I’ve been doing at university. |

Yeah, you really don't want a diesel with your driving pattern. It will be more trouble than what it's worth. Petrol or electric is the way to go.

Yeah I know but the car was given for free due to it being worth so little and I dont exactly have a big budget to change it to anything else.

I also have a 2.0D. I don't know the English prices, but I've recently had my glow plugs changed (all 4) with new Bosch ones. They were about £12 each here in Denmark and about an hour of labour to change them.
And the DPF, I replaced that myself this Friday with one from BM Catalysts which cost £190. If you can't replace it yourself, figure about an hour of labour as well for that. I don't know about the regulator. A new one is quite expensive, but might not need replacing. Hopefully someone who knows this will join the discussion. |

thanks, will look at getting the dpf changed then. Im not sure about glow plugs as the error code said it was coming up due to other error.
From reading online, dpf can cause glow plugs to go iffy and then the fuel thing is can also be caused by glow plugs that went iffy... |

First test your glow plugs; this is easily done with a DVM. They are used to raise the temperature of the DPF when the ECM detects that it's time for a regen; if they are U/S then no regen. They are cheap enough but can be a PITA to change if they don't come out easily. I wrote up the procedure that I followed about 2 years ago on this forum.
