There have been numerous reports of DPFs resisting regeneration if they get too full, and requiring a manual forced regeneration. For the DPF to have filled up completely to the point where regeneration was impossible within only 65,000 miles suggests some major bad juju going on there.
If your DPF is clogged and it keeps clogging, and if you’re doing enough low-load highway driving to support active regeneration, and you’re back at the dealership a dozen times for a manual regeneration in a service bay, the blockage is a symptom of a problem elsewhere. Guaranteed. And treating the symptom never cures the problem.
I drive 100,000 miles a year (actually in 49 weeks). 99% is all 65-75 mph. Just turned over 212,000 and my drivetrain malfunction light came on. One code that came on when I scanned it was "DPF: maximum mileage of the filter exceeded." Another code was the "SCR system: efficiency too low (filling level control, as well as SCR "metering")
I bought a new Vauxhall Corsa in November 2012, 2 days after having the car and only driving about 10miles the DPF light came on. Most of my journeys are short, say nine miles, clear roads, but I do longer motorway driving three days a week. My problem is that the light now comes on every second day.
How does a DPF work? A DPF works by trapping soot as it passes through the exhaust system to stop it from being released into the atmosphere. As with all filters, the Diesel particulate filter needs to be cleaned regularly, this is achieved through a process called regeneration.
The trapped material must be emptied or burned off periodically to “regenerate” the filter. That regeneration process may differ from engine manufacturer to engine manufacturer — so be sure to ask about these factors: Load requirements or limitations: Does the engine need to operate at or above a certain load for regeneration to work
Connect MX808 with OBD firstly. Before attempting a DPF regeneration, select “Auto scan” to scan the vehicle for engine codes, the DPF regeneration cannot occur while codes are present. Go to. Service >> DPF >> Hot functions >> DPF (Diesel Particulate Filter) manual regeneration >> Yes >> F-350 >> OK. Make sure the following initial
For the benefit of others: 1) Clear faults for engine. 2) Change to EOL service mode. 3) Login with code 27971. 4) Basic Settings > Service DPF Regeneration (cant remember the exact wording) 5) Long press the green button (it will say it exited due to safety) 6) Turn off engine (ignition still on) 7) Turn on engine.

Hi everyone, I purchased my 635d Sport Cab from a BMW Main Dealer in March - It was first registered in May 2008, and had done around 65k miles at the time of purchase. It's been great, love the car. As its an Approved Used Car from BMW it comes with a 12m warranty.
Because the DPF is under the car, not 'close coupled' in the exhaust manifold, the car needs to be driven quite a long way (50 miles) at 2000 - 2500 rpm to get the DPF hot enough to promote a passive regeneration. An active regeneration will happen automatically, but if the DPF is too stuffed up with soot for this to work, the post-injected
Posts: 56. Help please with DPF regen. M57 35D. Had the Particle Filter warning on the Dash, so looked at the fault memory with ISTA+ and saw the relevant errors were 480A and 481A. Did the pressure tests at idle and 2000rpm and found the pressures to be just under and just over the thresholds, respectively. Last regen was around 3500km ago and
