I have had my Trafic since new (July 06) and after just 3 months I had this problem. It has been back to the dealer a number of times (its booked to go in to be checked agan tomorrow), but they say it dosent show any faults so they cant do much! The EGR valve (?) has been cleaned out , but as you say the fault just comes back again. This is very annoying and possibly dangerous. If anyone can give me any idea what is wrong I can get onto the dealer.
