Last 2 weeks the cel has been on in my crd and throwing a code of p1265, I called the dealer and nobody knew what the code was and they advised me to bring it in at the next available appt. Well, 1 week later I finally get a appt, and they find 2 bad glow plugs! Wonderfull! And they cant get the parts for a week! And there fresh out of loaners. There diesel tech did advise that it is driveable though. Id plug it in but dont know how the condo board would feel about that. Getting down to the teens here and I just hope this thing start. So in less than 10000 miles bad glow plugs and a egr.
Still like the CRD though, just cant beat the feeling of all that torque!
I had the same error code right after the egr was replaced. That's a generic error code, it reads differently on the dealer scan tools. There it read P0671, P0674 on mine or glow plug fault on plugs #1 and #4. An ohmmeter check of these 2 plugs showed an open on one and very high resistance on the other. The correct resistance was .5 to 1.5 ohms. It seems if your egr fails in the open position, the burn temperature is too low due to not enough oxygen in the cylinders and the ecm keeps the glow plugs cycling too long to heat it back up and they fail prematurely. This would indicate that the ecm software didn't have the proper safequard built-in to keep excessivel glow plug cycling from occuring with fault conditions, but this happened before I had the ecm software update performed. One of those updates did change the duty cycle of the glow plug controller. Wonder if DCX software coders have any simulator tools to check for logic errors for common sensor fault analysis? I mean if a software logic analyzer that checks to see if components are range bound exceeded if a failed sensor input or anomoly causes an extended out of range condition or overcorrection. but I digress...
I would expect to see some more glow plug failures on those CRD's whose egr valve has been replaced, were overstressed, but haven't yet failed to the point where resistance is out of spec where a fault will be set. You probably have had some heavy black smoke on acceleration as well.
I also had to wait a week for glow plugs and this was back in the summer. I tried to buy a spare glow plug and DCX wouldn't sell it - they were on restriction. Once they were replaced the CRD was quieter and the smoke disappeared. Without overuse, the glow plugs should last a long long time.
