water in headlight, 2003 A6
 

I have a 2003 A6 with Xenon lights. One of the housings has water in it and
I want to pull the entire assembly to see if I can seal it up better. I have
removed 2 screws from the top side and the assembly is now loose, but
something is still holding it in. Any ideas? Also, any ideas on how the
water gets in the assembly?

Thanks,

Don
