One more observation. Not sure if just my car or same for everyone else. Compared to my E60, the auto rain sensor wiper doesn't seem to be working so well when rain is a moderate drizzle, despite having it at highest/fastest setting. Every now and then I have to manually swipe the wipers to clear the windscreen. E60 is fine though, even at 2nd highest setting. I hardly have to manually engage the wipers. Or is there any more settings (OBC programmable?) that I can do?
