The codes were p0300 fuel leak, which was probably from the fuel filter I replaced and the other is P0455 turbo code? The guy at the shop is saying the actuator plunger is gummed up and they have cleaned it and they may have it fixed , but my issue is also that when I go to bleed the system at the fuel filter there is still air in the system , what could that be related to and is it the cause not the turbo actuator. Furthermore what would cause that to gum up anyway. Thanks for looking into this ! I appreciate the help
P0300 is a multiple cylinder misfire and could be caused by a fuel system with an air leak. P0455 is not listed as a valid fault code, so not sure what this is. There are potential air leak paths at the fuel line connections out of fuel tank.
If the fuel is not being burned completely due to misfire it could produce excess soot and hydrocarbon that can gum up the turbo vane mechanism. Sometimes running the CRD very hard for about 10 minutes will get the turbine hot enough to burn off residual soot, etc. to allow full vane travel. Hope this helps.
