Other Fuel System Tank Assembly problems of the 2011 BMW 335

This is a know fault problem that is directly tied to emissions of the deisel engine starting at 2008-2012 for all BMW deisel engines. Maybe even newer models. This so called scr temperature sensor that is located inside the def (urea) tank fails, which in term fails the smog inspection if it is not replaced. Some owners and dealers have replaced this tank/sensor ( which is one part together, cant buy separately) under emissions warenty. But most dealers will deny the fact this system is the primary system of emmission. And if it's not working how intended I'm sure emissions of this car won't meetc the federal or state requirment. Please look into this and get this fixed/ added to the emmission system failure list.
