Thats low mileage and I do not think the DPF has failed and needs replacement. There is evidence that cars fitted with a DPF that do lots of short journeys never reach the operating temperature required to allow the DPF to burn off the built up soot. Are most of your journeys short? I also had fault codes...

I am learning to love the car again and do enjoy the drive but I'm not truly confident that it's all working 100% as it should. I can live with it as it is though. I've run 3 tankfuls through since the fix and all seems well. I'm getting a couple of mpg more than before.
