On page 9 of the 2011 X5 brochure (available for download on bmwusa.com), it shows a closeup picture of the new headlight assembly with the following caption, "...while centrally positioned foglights and Xenon Adaptive Headlights with
new LED Daytime Running Lights further distinguish the vehicle's distinctive front section..." I did not see any disclaimers.
Do you suppose they are referring to the new corona rings? The brochure also mentions the updated software changes, Mobile Office, bluetooth, etc. There may still be hope for the new lights on Sept builds...
