Thanks, all of you. I managed to get it open by accessing the splitter box through the wheel arch. Some say you can reach it through the inspection hatch, but the more of the liner you can remove, the better.
In my case, it helped that the fault was that the cable from the coupé had come loose from the splitter box. That way, I was able to yank the splitter box down separately to get a good grip on it, and then all I had to do was to pull. Worked like a charm.
