Simon has put a new sensor into the DPF but the issue remains, if i even slightly push the car at all the soot alarm comes on. (My push, i mean the slightest little acceleration beyond what an OAP on a sunday drive would do). Have been topping up with oil now for months but there is no oil under the car where it is normally parked. Have done numerous regenerations but makes no diff. Simon last week took the filter our and throughly cleaned it and left some cleaning fluid in it over night, then done hot power hose etc on it and still exact same issue.
Strangely, I went to Dublin from Belfast with the car and back about a month ago and there was no prob, on the motorway doing 80mph no issue. But next journey around town and back to square one.
I have spent so much on it now and drove around like a twit at 20 mph in totally inappropriate places that i am really ****ed off with the car. I just want it sorted once and for all. Have been quoted £450 to have the DPF taken out and car re-programmed and it is tempting. Or £650 plus fitting for the DFP change.
From what i have read here it looks like there is an issue further back with the car that is causing it to creating the material that is blocking the DPF, so would be really interested to hear from people with similar issues and what happened for them. Cheers. Eunan in Belfast.

Removing/Deleting the DPF, CAT or EGR is now a new EU inspired emissions and MOT inspection failure point.
I would try the following simple normal procedures:
1/ Liqui Moly diesel purge in the fuel filter every time it's changed
(Cleans the gum and varnish)
2/ Use expensive Diesel or a suitable fuel additive (LM, Lubriguard or BG)
3/ Run half a can of Liqui Moly/amsoil/Castrol Classic idle flush just before the oil & filter change (Takes 10 minutes at idle)
4/ Use the correct Castrol Edge engine oil AND change it every 5K miles (Leave the Volvo oil filter until 10K miles).
5/ Once all that has been done (It's just routine severe service schedule), go for a Sunday morning motorway session of at least one hour, OR fast main road with the RPM at max continuous (4K in 4th gear??) for 30 minutes.
6/ Get some motorway or Italian tune up time in every month.
7/ Fit a new DPF if you get another warning for it.
8/ If the oil consumption is an issue it's time for compression and HG checks (If the coolant is also going down).
9/ Any oil drips, try using Valvoline Maxlife 10/40 in summer, or a can of LM stop leak plus Ceratec.
10/ Irish Fish & Chips from a coastal town.
