Urea solution freezes at 23 degrees? Some bright spark at BMW is not paying attention. That is unsat, it makes the car undrivable at temperatures below 23 degees. What about "wind chill when the car in in motion, would that also freeze the tank? I wonder if M-B is having this problem with their brand of urea solution? I guess since the urea equipped cars are not sold in Europe then not a lot of attention was paid to what would happen in the colder parts of North America. Perhaps a block heater would help, but only if you were parked where there was an outlet. Back to the drawing board!
