New DPF question
Hi all.
Have just fitted a new DPF to my 2011 S80 1.6 D4164T, but am getting ECU codes relating to it, such as Regen Duration and Soot build up. A couple of times when driving the engine has cut out and proved difficult to start. There was a low fuel pressure issue but replacing the sensor seems to have cured this, VIDA not showing any issues anyway. Car also in 'limp' mode (3000rpm), but no dash warnings on this. Still learning about the car and as such was unaware of the DPF dosing tank until recently, got some fluid arriving today. I have reset the DPF counter in VIDA but not the dosing tank as yet. My question is, are the issues in all likelihood down to the dosing tank or should I be looking at another rabbit hole? Many thanks. |

Fuel filter issue gave me similar problems. Try a new filter.

you could try some cleaning fluid before the re gen to dissolve some of the soot

Hello
Was the replacement DPF OE or copy? It's not unheard of for copies to have pressure readings out of range from new. What reading are you getting at the DPF pressure switch? You are looking for less than 10mbar at idle and not raising much higher than 50mbar at 3k rpm. As well as registering the new dpf was the soot counter zero'd too? Also an empty dosing tank will trigger limp mode, so a refill of tank & reset of dosing counter plus manually activating the dosing pump to ensure it is running would be worthwhile. Forced regens are something to avoid. High temps crack DPF's which can be recognised by low pressure readings at raised rpm. What other DTC codes are logged and return even if cleared? |

DPF pressure sensor reading 5 at idle up to around 47 at idle, so that would seem okay. Additive tank now at 14/15 and counter reset, though I cannot 'activate' the pump in Vida. Info page says pump only becomes active after adding diesel to fuel tank? Perhaps someome knows more on this but it makes sense to me. I have also reset counter for new DPF again but couldn't see anything to reset soot counter? I did take a reading of soot mass which was around 1.0g. Car is now revving above 3k but throws the occaisional EML but no limp mode. Vida says these DTCs are: MAF reading in range but lower than expected. I have checked everything is 'tight'. Air Filter looks grubby so I'm gonna swap that out and clean MAF. Other one is DPF efficiency below threshold (Bank 1). Again, going to clean up sensors again. Thought I did this when changing out DPF but must have miised one. If anyone knows which sensor bank 1 relates to that'd be great. Thanks to all for help so far |
