Red DPF Light

So my RR A/B 4.4 SDV8 went straight to red DPF When I put OBD Tool on it said Soot Concentration was 9.27g/M3 and mileage since last regen was 4.07. How can this be. I also noted the Particulate Filter Differential pressure was reading 100000 Pa Surley this cant be right. Any thoughts would be greatly appreciated

Rather than jumping straight to live data, have a look at the fault codes. I'd expect to see a DPF pressure sensor fault

Red DPF Update

So I had left car a couple of days. Collected it to take to garage. Red DPF had gone. No error codes no limp mode. Its a complete mystery to me. Car going great.
I changed Oil & Filter as it was due. Examined pipes and hoses associated with DPF but could not see anything obvious
Any advice or opinions greatly appreciated
