All of the people posting issues with your sensors and def tank repairs, i think i am seeing a trend. Please answer in this poll if where you live is in areas where the temperature gets below freezing regularly. From what i have noticed most people that had these issues came from colder climates. While I know it is too early to tell i have not experienced any CEL's (except for a tire pressure guage going out and back in) and i am in a warm climate (south florida).
