Sorry, head to the Service Dept. When I took delivery of my first (and dreaded) 2007 E70 Launch Supply (one of the first batch)...The lights in question were not hooked up. Yes, you read that correctly! I couldn't understand why I couldn't see them at night, or especially in the garage or underground parking. I took it to the dealer, and they said that it somehow left the factory not connected. Maybe this is what happened to you, or the contact has been lost. Let us know. Good Luck!
