Other Fuel System Tank Mounting problems of the 2009 BMW X5

I own a 2009 BMW X5 diesel. BMW has recognized an issue with a sensor in the selective catalytic reduction (scr) active tank. The tank stores diesel fluid. Diesel fluid is added into diesel to reduce the amount of emissions that is released from the vehicle. BMW extended the warranty for this part but it is unknown how they determine the amount of this extension. My vehicle is over the extended warranty by 4 months but under the mileage limit by 40,000 miles. This issue should be a recall call and not an extended warranty with limited time to repair the issue. I attempted to resolve this with sean s. At BMW customer relations by informing him that this is my commuter vehicle and I have to drive this car every day. I also informed him that if not resolved this will lead to a large amount of pollution released to the environment. Sean s. Acting as a representative of BMW north America stated they are only concerned about their business and their bottom line and only will assist me if I'm a loyal customer. They viewed me as not a Smart business move to fix the issue and indicated they are not concern for the environment and ok for me to continue to drive this car that is putting out 10x the amount of pollution as gas. Researching the internet there are many BMW X5 owners driving their vehicle with this defective sensor and many using hacks to trick the ecu and many using alternative non oem parts and forcing a fitment. All of this is due to the limited time BMW is offering to fix this issue and the extreme cost of the repair at a BMW service center.
