Looked with scanner today and this is what I got:   time since last regen: 27744 S(econds presumably) oil ash volume: 0.1 L soot mass calculated: 0.048 lb soot mass measured: 0 KM since last regen: 156850 M(eters, actually not KM) Fuel consumption since last regen: 13.2L oil ash volume: 0.082 lb oil ash limit: 0.155 lb   Question: what's the deal with the limit? Is that the limit till a regen or limit till the DPF needs replacing? If it
