I have read a few comments stating that an Adblue pump failure caused a shutdown in frigid conditions. Is there any way to bypass this problem? Or what if the solution tank runs low, my wife ignores it too long, and the car won't restart? Is there a Plan B if you out in the sticks and your TDI won't start simply because of an Adblue issue - whatever it is? I know you supposedly get plenty of warning and 99.9% of the time there wont be a problem. I just don't like the idea of the car refusing to start simply because of an Adblue problem. It's not oil, fuel, or coolant.....
