Idling makes the percentage increase faster than any type of driving. This also gives you a good indication of when to expect a regen to start. I’ll plan a decent drive when it gets to 95%-99% so I complete the regen each time. The active regen starts when this gauge shows 100%.
Diesel Particulate Filter (DPF) Exhaust Gas Recirculation (EGR) Selective catalytic reduction (SCR) 1. EGR System. An EGR valve is mounted on the exhaust manifold. This valve regulates exhaust gases that go into the engine. A portion of the exhaust gases is re-directed from the EGR cooler, through various pipes and routes into the intake manifold.
When the DPF warning lamp comes on (check your handbook to see exactly what the one on your diesel looks like) it’s time to take the vehicle on a longer run, preferably on a faster road such as a dual carriageway or motorway. Driving at 40mph or more for 10 minutes should prompt the DPF to go into ‘regeneration’ mode and burn off soot Because of these sensors, if you delete the DPF or do a DPF bypass without a rewrite of the engine management computer, it will set the check engine light and the car may not run correctly. In one case, a DPF delete before the replacement ECU flash melted the reflector because of the excess fuel during an attempted regen cycle. Minnesota. Jan 23, 2022. #2. Not sure it is required at 50% but below is what you should do at 80%. Could be possible that nothing happens at 50% when you perform the below steps. Not sure. One section states: The Cummins® diesel engine meets all diesel emissions standards, resulting in one of the lowest emitting diesel engines ever producedThe warranty book states that the recommended maintenance schedule is not affected as it relates to DPF ash loading, but it also specifically states that the DPF IS covered. 81,000 is far short of the recommended maintenance interval of 110,000, the first time it's to be checked. The DPF idiot light has not come on, just the check engine light
