Even in MN, @ 3 years and 50k miles. nothing should be rusting to the point of failure on a BMW. Maybe the line just lost some kind of seal. I dont know, they never showed me the problem first hand.

This sounds exactly like the leak I've had. My car had a lot less mileage though .. but cold weather, snow/sleet and salt may be the contributing factor ...
