Adblue - BMW answer to Volkswagen

A storm brewing that can have very negative impact on Volkswagen. But what about BMW. Did BMW designed its diesel engine cars to be EPA friendly?
As a BMW diesel car owner, I had no idea that modern BMW diesel engines use Adblue - a fluid that is used in the urea tank to improve emissions. This fluid must be replenished periodically and running out of the urea exhaust fluid will prevent the engine from starting.
