My 2007 D4D has probems starting when cold. It fires then cuts out repeatedly sometimes requiring 5-6 attempts before finally running. I have changed glow plugs (one failed), fuel filter, air filter and cleaned the egr valve but nothing has made any difference. It went back for the head gasket recall a couple of years back and is not using water so don't think that is the issue. No fault codes are showing on my reader.
Don't really know what to try next. Can anyone help?
