Flies In The Headlight Unit

[Tourer]

I had the RHS (Driver's side) headlight unit changed some time ago because the Auto levelling system on the old one was playing up.

However, since then I have been getting flies in the headlamp unit. I kind of lived with the dead fly and then today I saw a couple more flying around in there.

How do I get to the headlight unit and can I get into it to resolve this problem? i.e get the dead flies out and seal the darn thing!

Any one know?

To get the lense off you need to pop the whole thing in the oven to heat the sealant up enough to pry the lense of and then reheat it to put back.
