Thanks for the info, X5 Meister (good to see you back and participating with all the great info you bring.)

Just to let everyone know, I have not taken my X5 to the dealer yet; the problem has stopped on its own. I thought perhaps I had opened/closed the pano roof and it didn't make proper contact before, and now it is making one.

It is going to rain heavily this week in San Jose area (good, we need the water in the region, running dry for the last few years.) I will update again if I see any more leaks.
