Hi all, This is my first post, I have a lovely 2005 23,000 mile van, yes only 23,000 miles, converted to a camper. I have owned this van for two years and it has always started and run perfectly. But last weekend this came to an end I experienced loss of power and rough running above 2500 rpm. If I start the van it starts and ticks over perfectly, if I then push the revs up to 2500 all is smooth but above this it all turns bad, the engine runs very lumpy and sounds horrible with lots of white very diesely smelling smoke. I have had this analysed and the plug in device came up with map sensor failure, I purchased one of these (£89) and fitted it there was no difference! I then replaced the fuel filter,(which seemed pretty new) I filled this with injector cleaner and a little diesel and started the engine which seemed to run much better initially but soon reverted to rough running and smoking. Where do I go from here? possibly EGR valve off and clean, (do I need new gaskets to do this?) what do I clean it with?. Then I guess injectors, I have to add that when I manage to rev through the rough running at just over 2500 rpm and 3500 rpm all seems to go back to normal with smooth running and no smoke at and over 4,000 rpm. I am not a mechanic but just a "back street spanner man" with very little talent!! Please help, I'm sure someone else has experienced something similer to this. Dave.
