Anyone have any problems with the CEL coming on multiple times? Had mine come on for the first time this week just in time for a second oil change at 10k. The dealer went ahead and did a reflash on my tranny and NOX recall. Got my truck back yesterday late. Drove 40 miles today with a warning message in the info display that says "drive to clean exhaust?" Saw a regen message shortly after a quick stop at a store. Drove 10 miles more and a CEL came on. I then drove around 20 miles with drive to clean message again, then gave up and parked it. Never seen a warning message like that before on the info display. Mileage was horrible all day.No mods to the engine and not tuned.. Any ideas???

Dealer gets in the AM regardless....

 

I had a CEL light come on and the truck was always wanting to do the exhaust cleaning. It turned out that my DEF pump was going out. The dealer replaced the DEF pump and everything's been "good to go" since then.

 

After the third trip to the dealer this week and two reflash attempts, I was told the EGR cooling valve needed to be replaced. The dealer said they had two other SD trucks in there waiting on the same part on backorder. Whats that? 3 weeks? Ur killin me smalls!

 

Three weeks, ouch.
Is that valve within the EGR unit and will they replace the entire piece of hardware?

 

Honestly i have no clue where its located. I wanna research it tomorrow when i have some free time.

Forgot to add that after driving it today for about 10mins the service light kicked on and the truck went to reduced power mode. I killed it for 20 mins at my shop, then restarted it to bring it to the dealer and the service light went off with the CEL still on. Of course the dealer is luckily only 5 miles from me...
