Thanks for your reply.It should but it will block at sometime and it's not doing engine any good as it can't release gasses as good. I had mine removed and the van is good on fuel and power is better

Do you get a warning when you need to do this?Just take your van on a run along the motorway that usually clears mine
Adblue is to reduce oxides of nitrogen (NOx) where the dpf filter is to remove the soot. New diesels have both adblue and a dpf filter don't they?They are a flawed technology to begin with and a real pain in the butt!! The ECU is programmed to pump extra fuel into the system to raise the temperature enough to burn the soot off. If you interrupt a regen cycle then it begins all over again the next time you drive. During a regen you will average about 10mpg and they can take upto 25 minutes to complete. Usually there is no notification light or anything to tell you when a regen is active- only when one MUST be completed because the filter is dangerously full. The adblue system is much better IMO.
I have heard two things about this. Every 300 miles regeneration takes place and you should around this mark, hit the dual carriageway/motorway to maintain at least 50 mph at over 2000 revs for at least 10 mins. the other one is Shell v-power premium which has been made to eliminate the need to go for such a drive. Life of these filters are 80,000 - 100,000 miles and then it gets really expensive.
As far as I'm aware, Adblue is added to the fuel to aid the heating process. It's not so much the soot but the hazardous content of the soot. If you expose the soot to a high enough temperature, for long enough then the hazardous part is neutralised and the remaining soot is safe- or safer. Some DPFs are further away from the engine than others and so require extra heating.Adblue is to reduce oxides of nitrogen (NOx) where the dpf filter is to remove the soot. New diesels have both adblue and a dpf filter don't they?

Can a local garage blank off the egr? Having problems with eml and at the moment.I'm considering having the DPF removed from our car. You remove the filter internals so that the DPF is still visible for MOTs and then the regen process is written out of the ECU.
I had the EGR blanked off on my 1.6 Hdi Dispatch- best thing I ever did. No smoke anymore, no EML and not an issue with emissions for MOT.
