Hello! I'm totally green about this but making an effort to get help before I go crazy. Have a Skoda Octavia 1.6 TDI 2012 with problems with DPF regeneration. The DPF pressure sensor has been replaced twice. Sometimes the regeneration starts and it works several times in a row, but if I turn off the car during the ongoing regeneration, it won't start again. Then I have to run a forced start of the regenring and run and it often jumps into action. When it doesn't work it seems to be running but the only value that goes down is soot mass Measure(g) which goes down very fast but not Soot mass Calc(g) (when it works both go down) Thanks for any advice and help I can get, but keep in mind that I'm completely new to this. However, I want to try to fix it myself and avoid a workshop. EDIt: As in picture two is when it works, the difference when it doesn't work is that the Soot mass Calc(g) doesn't immediately drop anything, maybe -0.2 very slowly. All other values are roughly the same. and - the value of mg/km is somewhere between -19 - -40 when it does not work. (when it works it is between -1500 - -3000)
