Was just reading on the differential pressures at idle (across the DPF).
At 100hpa (1.45psi) The dpf reaches the end of its service life (Ash needs removing, or very clogged with soot from lack of regen)
Normal values are < 20hpa (0.29psi).
I think the 6900kpa (1000psi) may be an erroneous reading. Thats kind of combustion level figures. or maybe its 6900hpa? still huge. Even the AAs figures are huge.
Im now very curious to see what mine is!
