Maybe the guage was not accurate.

It appears that Ford, as well as many other mfg, has used it on several model years ago.
My 2001 X5 has it, but I thought that it was just another one of their cutting edge technology at that time.

The powerstroke series diesels all had throttle by wire since 1994, when the powerstroke first came out. The older none computer diesels were from 1983-1993.5, and had accelleration fuel flow controled completely by direct cable linkage, and a mechanical RPM governor (3300-3700 rpm).
I would also like to hear more about this incident.
No I was not referring to you (at least I don't think so). I was referring to the post where the guy had his truck run away with him and could not stop. Had cops chasing him .....

Diesels have a peculiarity in that they can "Run Away". This usually occurs when the crankcase has been overfilled. The engine oil gets sucked past the rings and is ignited in the cylinders causing the engine to run at maximum speed. No amount of governor actuation will stop it. I saw this occur on a Cummins diesel generator once. They had to block the air intake with large rag to stop it. I dont know it the 6.4 is capable of such nastyness

The old 6.9 diesel has a way of burning large amounts of oil if the CDR valve gets clogged, but not once have I ever heard of a 6.9 running away except for an incorrectly assembled injector pump.
I can't imagine that much oil getting past the rings of a brand new engine either.
Now if the turbo oil seal blow out, soposedly that can also cause the a runaway condition. But I think there would be some smoke to indicate all the extra oil going out the tailpipe.
