DPF regeneration has not occurred in the past 10,000 km.

Dear All,

I possess a 2010 BMW 520D F10. I assessed the DPF status using an OBD2 reader and obtained the subsequent data regarding DPF regeneration.


DPF - Distance Travelled Since Last Regeneration = 16,507 km (~10,257 miles)
DPF Engine Operating Time Since Last Regeneration = 3010 hours, 5 minutes, 20 seconds
DPF-Exhaust Gas Differential Pressure = 95.99 DPF-Soot Mass = 45.99 DPF-Status, Total Remaining Distance = 83,440 km

I do not have any notice regarding the DPF on the dashboard.

Could you assist me in comprehending the aforementioned readings? I travelled 60 miles last night at an average speed of 65 mph and have undoubtedly covered hundreds of miles in a single journey over the last 10,000 kilometres. What caused the DPF regeneration to fail? Thank you.

The prerequisites for regeneration have not been satisfied for some reason.

The passive regeneration must be functioning effectively; otherwise, the DPF will be completely obstructed after 10,000 miles.

Thank you. Is it accurate to presume that DPF regeneration occurs only once a specific threshold of soot mass is attained, such as around 50 grammes? Should it occur every time you drive on the motorway for around an hour?

Only upon reaching a specific threshold.

Does it definitely have a diesel particulate filter?
