Check Engine Light On and Off
 

I have a 2007 2500 Turbo Diesel and on occassion, the check engine light will come on and then after some period of time will go out on it's own. It reappears later. I don't have a way to pull the code. Any others having this problem?

Have you tried the key trick I dont know if it works on the 07s but you turn the key to on dont start then back one click do that three times leave on after third time watch odometer. Also you could fill out your sig. so we know exactly what youve got

If you have the 6.7L Cummins, Dodge has been coming out with regular "flash" updates to the engine control software to take care of the check engine light problems. Take you truck back to the dealer and ask for the latest flash.
