On a 2012 Passat 2.0 CR with a genuine VCDS 16.8 at advanced measures on particulate filter I have:
IDE00427 Particle filter: difference pressure 3 hPa
IDE00428 Particle filter: offset for differential press. 0 hPa
IDE00433 Particle filter: oil ash volume 0.08 l
IDE00434 Particle filter: soot mass calculated 15.32 g
IDE00435 Particle filter: soot mass measured -0.39 g
Why is the soot mass measured a negative one? In 3500 km the oil ash volume was increased from 0.07 to 0.08, is it normal? The last regeneration was 860 km ago. Yesterday, with the engine at 90 degrees at a short stop the engine fans were at high speed the idle rpm was 1000 and I thought that the regeneration was started, but the values posted here are after that. Should I worried about DPF?
