P242F Diesel Particulate Filter (DPF) blockage/ash accumulat
Discussion
Not a car as such but my brothers 2014 Renault 2.0 diesel van.
The engine management light is on, after reading the codes I got the following :
P242F - Diesel Particulate Filter (DPF) blockage/ash accumulation
P2002(92) Particulate Trap, bank 1 - efficiency below threshold
P2002(91) Particulate Trap, bank 1 - efficiency below threshold
Delving a bit deeper it says there is 4.4g of soot which doesn't sound a lot to me. The interesting thing is it says 106337.52 miles since last succesful regeneration which suggests it has never regenerated.
As I said 4.4g doesn't sounds a lot, is it possible that another sensor has failed triggering this error?
I only have a cheap eBay bluetooth ODB2 adaptor and Car Scanner on my phone, is it possible to force a regen using this?
I am tempted to get him to drive around the M25 in 5th gear to see if that forces a regen.
Or is the only option to take the DPF off and get it cleaned?

These are the only codes :
One of the pipes to the DPF was split in the past and has been replaced. Could it be possible that the error is not caused by a blocked DPF but rather a sensor issue or a blockage in a pipe from the DPF to the sensor. I find it interesting that the data below states "Time Since Last Regeneration = 0.49h"
My plan of attack would be to check the pipes going to the DPF pressure sensors are good and then take it for a drive around the M25.

Maybe worth looking at orileys autos on YouTube. He does lots of blocked dpfs.
I think he mentioned before that some manufacturers just declare the dpf full at 100k + miles as the ash calculation maxes out.
Cars can’t measure dpf ash like they can soot, so the ash value is typically calculated and deemed full by some manufacturers at a given mileage.
He cleans the dpf with cleaning fluid, checks the differential pressure is ok and then tells the car it’s got a new dpf - seems to work ok as the manufacturers are quite conservative with the ash calculation.
