Hi again, just another idea about waterpump plastic impeller came off and does not rotate when engine just started. I had that but when temperature goes below 0C. Eventually it will stop rotating with WP shaft when driving and engine overheat as result... And all depends from your reaction next.
May be no much logic for you in this idea but i experienced that and its pretty common for bmw.
Good luck.
