'59 S80 2.0D diesel 'DPF' clog up short running around town?
Clogged diesel particulate filters (DPF) certainly used to be a problem for diesel engines after too much short distance, low rev, cold running... typically repeated short trips around town without the benefit of a longer, hotter run.
A regular burn out from a 'hot running', higher rev run was the maintenance antidote; failing that a trip to the dealer for an (expensive) DPF 'regeneration' was required - generally in response to a very pronounced loss of power and a dash light. Is my understanding... so far... correct? And would that still be the case for, in particular, a mid-09 S80 2.0D? Or would short running still present a clogging risk to the DPF system? And/or would any other problems be likely to occur from 'too much' short running of this particular diesel engine - apart from how all engines in general suffer as a result of short runs?? Many thanks. |

Since seen 'Diesel' section and the answers are there. What a can of worms DPFs present! Apologies for posting in the wrong section..

I have an 09 2.0D and I've not experienced any problems with the DPF which surprises me a little.
For example I can often spend 2-3 weeks just doing short journeys in town, typically 10-15 minutes long. I do a longer run of at least 15 miles including some motorway at least every 3 weeks. When I do a longer run I can tell from the instantaneous fuel consumption reading that a re-generation is being carried out. I do tend to use premium fuel which may generate a little less soot. That's my experience which has been positive. |

I have driven S80's for a long time including the D3 2.0 ltr and have not noticed a issue. In the past it was true that diesels would benifit from a blast out but this was more to do with cleaning injectors. The new engines do not seem to suffer from the same issues. The filter does auto clean and goes into the engine oil, if engine levels go up it is over cleaning and will bring up the orange warning triangle, if you are using too much oil it might not be cleaning enough. On a 59 plate (if still under warrenty) you should be able to get this checked out at your dealer. I have also taken fuel from any source, at the end of the day it all has to meet the same EU specifications.

You may want to take a gander at this:-
http://www.volvoforums.org.uk/showthread.php?t=99488 There has probably been more natter here on this subject than most. In essence, first, have you had the recall done and the software updated?(only applicable to D5 engines) Second, these cars were never intended for short "in town" use, the software will prompt a regeneration roughly every tank of fuel, if the drive is no long enough it will prompt again when conditions are right. For a sucessful regen the car needs to be up to temperature, and the process takes 15/20 mins at motorway speeds. Continued regen failures due to driving times/conditions will results in a DIM message, and a trip to the dealer. The regen process does not intentionally dump anything into the engine oil> this was what the software mod fixed on the D5 variants. The idea of the regen is that soot is burnt off at V high temperatures in the exhaust gases, sort of a CAT for diesels. If the car never gets hot enough for a sucessfull burn, you will get a full DPF.
