This van had no power and had 12 psi of pressure upstream of the DPF, this was too high to allow it to carry out a static regeneration, I put a T connector that I had in a vacuum gauge kit into the hose going onto the DPF pressure sensor.
This lowered the pressure a little bit, although it was not enough to allow a regeneration to be carried out, I ended up fitting three T connectors in series on the pressure sensor's hose. This was enough to carry out a static regeneration.
After I did this and removed the T connectors from the van, I carried out a second static regeneration, this got rid of all of the exhaust pressure.
There was no faults on this van causing the DPF to block up, it was just a blockage caused by driving very short journeys every once in a while in the most economical way. The van never had the chance to regenerate while driving.
I hope this helps
Thanks for watching.
