DPF Full IID halts regen after few seconds HELP

had a MAF Sensor go faulty and had to do 230 miles before I could replace it. now replaced but DPF is showing as full, I have tried to do dynamic regen using IID but after initial start it says regen halted, tried a couple of times but same result. has anyone got any ideas why it is failing.

Thanks in advance

Is the fuel tank low I believe it needs to show at least quarter full before the Regen will work

yes half a tank, i have tried putting old the maf sensor back and the new sensor in the front position and still no joy on getting the regen to work currently showing 40.5g on the DPF and rising with every try to regen. not sure what else to look at. Big Cry Big Cry Big Cry Tintenter

We have it at work where the dpf is so full the vehicle knows it cannot carry out a regen, so stops the regen.
New or cleaned dpf is the cure, but they still need a function test/regen to tell the car it has a new/cleaned dpf.

thanks for the replies, looks like it will have to have the DPF off to be cleaned currently showing 44.5g of soot via IID Tintenter
