The cost of DPF regeneration can vary depending on whether you have it done by a dealership or perform it yourself using a professional scanner. Dealer regeneration: DPF regeneration costs between $250-$800 at a dealership, as dealerships typically charge a premium for their services. The exact cost will depend on the dealership and the type of The first regeneration didn't occur until 10,865 KM in October of 2014. Then through our northern winter it regenerated approximately every 1,000 - 1,500 kms. I expected that come spring the frequency would return to the first summer of operation. Not so. At least once a month it regenerates and still about every 1,000 - 1,500 km.
This is called passive regeneration. DPF regeneration (active) Some cars don’t use the motorway often enough. When the accumulating soot reaches about 45%, the DPF switches to active regeneration. The car forces higher exhaust temperatures, burning the soot in the process. Failed DPF regeneration . In towns and cities, some cars do not reach
Anyway, you should be able to look at the egt's from each probe on your edge. The one for the dpf will lag a little behind the post turbo one until you go into a regen. In regen, the one monitoring the dpf will climb to around 1000, while the front one will be about normal. Mine stays in regen and tries to maintain the 1000* for about 15-20
ACTIVE Regeneration Trucks that drive local routes and rarely maintain typical highway speeds for extended periods rarely meet the conditions for a passive regeneration. In these cases, an active regeneration occurs.
I would like to point out one thing the 90% is not a indication of how much the dpf is plugged . It means the soot is at 90% of dpf capacity . The engine does a regen to change soot to ash , witch takes up a lot less area in dpf filter . that is why you see the % going down during regen . As far as cleanable dpf filters caterpillars smallest
