    My 745i windshield suffered a fatal stone fracture and was replaced by Guardian
    by a nice Pilkington. While the windshield was out, a shower required us to move
    the car. After reassembly the rain sensor was inoperative; we eventually
    determined that the computer had decided the car had no rain sensor and had to
    be reinitialized by a dealer.

    Do other models behave this way and can this problem can be prevented by keeping
    the ignition off while the sensor is unplugged? These little gotchas can cause
    a lot of trouble!
