Maybe not. I think the goal of this was more epa/mpg cheating. Just like the stupid cutting the motor off at a stop. Just a way to cheat the mpg numbers.


With a diesel they don't have the same "need" to cheat I would imagine. Plus if you don't keep a diesels battery fully charged your going to get cranking problems and pissed off customers.


To risky to try the cheat on those.


Again all guessing but I could see this playing out that way.


Volt meter will tell you right quick. It loves to stop charging while driving. If you never see it dip under 13.8 or something then the diesel isn't doing the no charging stuff.
