Before I break anything :), does the plastic guard on underside of the boot lid that covers the spoiler bolts just pry off?
For the most part, though there are several screws and some plastic clips on the inner part...
OK, you need to remove the plastic trim from the top of the glass (washer jet) around to the bottom. Then the bolts/screws come undone from there.
