So I got this error a week ago (MC Mondeo), and eventually managed to force a burn to clear it, and have been monitoring the DPF since. I've noticed the soot load goes up to 80-85% (about 8g) every 150-200km, and has done a few burns by itself since then. Is this about right? By chance I was doing a fair bit of highway driving, but am wondering what happens when doing mostly city driving - when the soot load gets up to high levels?

I've also been monitoring the DPF differential pressure - it changes a bit depending on load, but seems to average around 4kpa, but varies from 0 - 12 when running normally.

Have also noticed that the fuel consumption seems to sporadically be higher than normal - I usually run about 5L/100km on the highway, but was up at around 7-8 for a bit, but then dropped back down. This was not during a soot burn btw.

Any thoughts?
