headlight assembly - questions

[96ce]

Hi,

I am hoping I can get some help from this forum. I have a 2001 X5 4.4. The passenger side headlight assembly has a lot of condensation in it (more like heavy water droplets). I would like to change out the assembly without going to the dealer. So here are my questions:

1) How difficult is it to remove / replace the entire assembly;

2) What should I replace the assembly with? My X5 has all options so I think it has the xenon light option?

3) what's it going to cost me?

Thanks so much. I hope to one day have enough knowledge to begin to pay the forum back for is help.
