I reckon most would probably think the same as me - swap your angel eyes headlights for some oem ones, preferably some xenon units from a 1*2. Angel eyes should be reserved for BMW's as far as I'm concerned.
If you really want to fix it you're probably just gonna have to take it off and have a look for yourself (unless it's accessible from the engine bay, which I doubt). Although I can see it'd be better to have some prior knowledge, otherwise you could end up having to re-fit and re-align it, without even having fixed it, just to get your head around what needs doing.
You could get lucky, there may be someone on here who has fixed one previously.
