I wonder just what the ECU "upgrade" does then? I will be very interested to hear what ExNissan thinks about this as it was his post about not seeing any passive regeneration on his long travels that made me curious why nothing shows on the % readings unless a burn is happening.
So just to be clear we think that the ECU computes the % from the fuel and distance, then decides the DPF is full and starts a burn.
While this burn is taking place the ECU computes the temperature and length of the burn and assumes the DPF is now clear?
ExNissan explained in post 21 that to get a useful reading from the differential pressure sensor the gas volume would have to be taken into account as well.
As there is no sensor for this (afaik) then this differential pressure sensor is only used to detect a partial or full blockage?
Does this mean that we may all be using diesel to heat the DPF to 500 odd degrees when it may not be necessary at all?
