I just found out that someone has written about a way to fix the self leveling headlight center adjusting post breaking problem ( Name on the net: Brutal) by inserting a screw in the plastic chrome adjuster under the radiator cover. See Jaguarforums.com

Headlamps pointing very near in front of car. Jag dealer has stated over the telephone that this is a piece that is broken. I stated it would be coincidental that both have broken simultaneously but he says it is broken and the adjusting screws will not help.
