Good morning all, iam hoping that this is the place to answer my problems..............

I have owned Ford transit minibuses for many years and upgraded my two mark 7 17 seaters for two mark 8 17 seaters last year. They are a joy to drive but I have just started to get a problem with them. The dreaded engine malfunction light has come on the dash board and after plugging in various diagnostic tools they all tell me the dpf is clogged and needs a regeneration. Now this is where the problems start, I live on the isles of Scilly and have 9 miles of road none of which is suitable to doing a passive regen as I can't get up more that 40 mph for five minutes if iam lucky!!! There is a small garage here that has diagnostic tools but none will allow a forced regen, they all get so far and then say there is not suitable information! Does anyone know if you can purchase a diagnostic tool that is suitable for a euro 6 engine so that I can do the regen myself or should I take out the dpf and have it remapped by an expert. Failing that I will have to sell them and get something that hasn't got a euro 6 engine in I guess!!!!!!!! HELP!!!!!!!
