On my 2010 it turn the engine light on when I was pulling my rv. They was a small shop that look up the codes for us and got the engine light to go off. The code said it was to do with my turbo. When I took it in to Towbin Dodge the said there were no codes on it after they had it for days. My question is are the codes not logged on the computer even if the check engine light is not on? I have the Dodge extended warranty. Are they just giving me the run around?
