I had codes on my 07 since the day I bought it. I finally had them buyback the truck and got an 08 for 1200.00. They compensated me for all add ons. They wanted difference of msrp.s also but I refused that. After alot of phone conversations and great help from the local dealership I was able to settle. They have a formula for milage to money. Mine was on 3200 miles I believe. That was taken from the 3rd time I took the truck in for the light. All miles after that were not counted.All were emissionn related problems. My new truck been back two times but has been ok for 2000 miles so far. Make sure you let them know you are willing to go all the way with this even if it takes a lawyer because you may have to. Keep records of everything, phone calls and names included.I think my deal was fair but sure was aggravating. Good luck.

 

Welcome to the forum. Try tightening your fuel cap. You will get a CEL if it is loose.

 

Tried this as this was my first suspicion. Turned out to be not.

 

Took it to the dealer, the dealer tells me that the turbo needs to be cleaned and they referred me to another dealership. I think the fun is just about to begin... Hope this thing will never come back. We'll see.
