My 400i has got a recurrent problem with main beam selection: When the switch is put on to Main, the lights retract, as if the relay's not getting any feed and thinks I no longer need any lights. Could be dangerous. I'm glad I discovered the fault while checking somehing else, and not on a dark night!
The main headlight extension relay was replaced by a specialist, but the fault's back. Anyone out there got the same problem?
As an aside, I'm finding out a few more things about my car. The actual colour is Sera Blue Metallic, not Ribot as previously thought. I'll amend the listing and add pictures...
