Well, the dealer told me to put the BMW Fuel Additive $16 in the tank at full level and to add a second a full level and the light has since cleared itself. They found nothing mechanically wrong with it and they got BMW to assist in the diagnosis. My guess is the vehicle was bought as a REPO and I believe it sat somplace and built up carbon and who know what in the engine and the injectors. Worse case scenario I've been told is that I will need a Catalyst Converter. No codes for it yet though and I won't be replacing Bank 2 anytime soon as the vehicle only has 77k miles on it. Thanks everyone for you input.
