Hi all. I have a V40 D3 on a 63 plate (5 cyl engine). Soot filter full message on dash last week, so took it up the motorway for 40mins to try to clear the message, but no joy. So, I got one of those DPF cleaning companies to come round. They read the fault codes and concluded that the DPF was not blocked and the fault was with the pressure sensor. So, I took the car to a reputable independant Volvo specialist, who confirmed the fault message and the fact that the DPF was not blocked. He changed the sensor, but the message remained, until he did a forced regen of 1.5 hours duration! Surprise surprise, three days later and the message is now back. I've read a couple of posts from people with similar issues, but none of them conclude with what the actual fault was, so I'm hoping over the fullness of time, there may be others who have had experience of this issue and are able to advise? Thanks!
