Default help and advise please

I have had the dmf squeek happening on my car recently and wanted to get it running right before I replace it, I have only recently managed to talk to my engine ecu which threw up a few faults, I have replaced the glow plugs and managed to get the ecu fault free apart from a turbo under pressure fault which comes up now and then. I believe from researching this may be something to do with the dpf not regenerating correctly (glow plugs were all knackered and God knows for how long) strange thing is no warning on the dash that the particular filter is blocked requires cleaning, the car is a 307 sw 1.6 Hdi engine code rhz, I have planet and have clocked a few hours on it but by no means a pro, what I have noticed which worries me is the particulator filter is 100% full, the measured air intake is constantly 900 degrees?? I have checked the engine ecu is fault free and coolant is set at the right temp and attempted a stationary and moving forced regen to which I get the display rege impossible... The reason I'm attempting to regen is to try to clear the filter down from 100% and hopefully that will sort the low pressure on the turbo and it will run a lot better, can anyone give me some pointers as to what to try as I'm running low on ideas ( apart from replacement /cleaning the dpf- dont want to remove and remap ), does any one know if the forced regen won't take place as it's over 95% ??? Also is the air measured temp a sensor and could this stop the regen proccess???

You can just remove the DPF and wash it out this will do the same as a forced regen and the car will run better with it cleared out then you can figure out why its not doing it itself.
