I can't seem to be able to get this car to carry out a DPF regeneration, even though, as far as I can determine, the soot level and pressures are within acceptable limits.

The car is in limp home. If I go in to adaptions, channel 2B - Service regen whilst driving, I can then drive the car without loss of power. I've driven it for around 20 minutes on main roads but so far I still have the three engine and DPF warning lights on and it looks like (from the data above) its not initiating a regen.

When I go into that channel 2B, it displays stored and new data as 00 00. I'm not sure if I'm entering the new data correctly, but it accepts 01 00 and displays this in stored data as 00 01. I'm not sure if this correct?
