paul.h Posted March 11, 2016 Share Posted March 11, 2016 Welcome to the forum. Which engine do you have, how many miles and is the servicing up to date including replacing the fuel filter ? Has the engine management light come on and have you had any diagnostic checks ? Have there been any mods such as the dpf being removed ?

paul.h Posted March 12, 2016 Share Posted March 12, 2016 You could check for any air leaks after the MAF but also on all the hoses connected to the sensors/actuators. Also check if the air filter is clean. Then it may be a case of a diagnostic check and maybe checking the fuel injectors. Quote Link to comment Share on other sites More sharing options...

kevin maynard Posted March 12, 2016 Author Share Posted March 12, 2016 Sometimes it will fine but then it runs rough again and you get a sort of diesel tapping noise Quote Link to comment Share on other sites More sharing options...
