let us know how you make out at the dealer.
This morning after a couple short trips to the store with the CEL on I headed to work about 50 miles away. After about 5 miles the light light shut off so i figured it must have just been a fluke. Them about 10 miles later the dpf light came on and a message that said exhaust fluid quality poor, derate to 65mph in 99 miles. That lasted about 7 miles and shut off and now shes all back to normal...I dont know whats going on hahalet us know how you make out at the dealer.
