“Def light came on and the display saying service exhaust fuel system and refer to manual. That gave me nothing. The codes that came up is p2209 and p20b9. So the heater in the def tank is broken and the nox reading is wrong or has gone out. Then my speed was reduced to max 55 MPH. Dealer said it would be $1500 to fix but after reading forums on-line there have been a lot is issues with the def system, fixing it, and then still displays issue. Am I going to get this repaired and still have an issue like others?”
