Thanks for letting me join, got the truck cause it fitted my needs, down sizing from 3500 and 5500, no more heavy pulls, really like the truck, cannot complain about the ride with air susp., after coming from my last trucks. Just had my first CEL, P24AE, PDF sys, so took it in for oil change and tons of updates on ECM, my only complaint so far is why dealers depend so much on ECM updates to correct CELS. They said the updates would correct it, we'll it did not and going back in this coming week to get fixed. If they would of only taken a few min to use a volt meter to do basic trouble shooting to find the problem, but they think I guess the up dates to the ECM is fix all for a lot of problems. Under warranty so all is good, just time that is hard to come by at times when you have to take it in multiple time to fix. Again thanks for letting me join, I do not do a lot of chatting unless I have some info that can be informative. Hope everyone had a great Christmas.
