DPF sensors
I am still getting the dreaded soot filter full message so am going to have to start looking at what is causing it. How many sensors are there on the DPF which control the reading which triggers the soot filter full message? I am thinking of buying a new dpf and sensors although I will probably replace the sensors first.

What do you mean by that? Did you already try to replace sensors, delete trouble codes or something else?
DPF has 2 sensors - 1st is exhaust temperature sensor and 2nd is exhaust differential pressure sensor. The best would be if someone plugs volvo dice and reads live data

Got the message in a month or so ago and after a week of trying to get it to sort itself out with long runs etc I took it into to Volvo for a forced regen. Lasted about 2 days then was back in again. Would the sensors show a fault if they were faulty or would they just read high pressure?

Some Model year 2010 cars suffered failed temperature sensors, mine being one of them: I got the "Engine System Service Required" message.
Your problem would seem to point to a DPF problem rather than a sensor problem. Did your dealer not do a fault code check when they did the regen?

yes they did and the fault code was related to the DPF, never mentioned the sensor.
