I have been battling the code for a couple of years now. The truck has been to the dealer multiple times to try to get it fixed and the last time I went (roughly a year ago), I believe they even "said" that they replaced the glowplug module along with a couple of faulty glow plugs. A couple of days after that visit the code was back, but stopped coming on durring the summer and early fall. Well a couple of weeks ago, p064c came back and now a couple of the individual glowplugs are bad as well. My question is basically what would you guys suggest my next move be. Obviously I need to replace the glowplugs but I have no idea what to do about the module.
Thanks
