Like Les said, it's nothing more than getting over the loud snapping noise from pulling it off once the screws are out. It's your typical MINI panel...a few screws and the rest is held on with plastic clips that come free with a little persuasion. I can't recall since I haven't been in a first gen in a while, but 4 sounds about right. I don't recall there being any hidden or secret screws on that panel. In my experience these clips don't have an issue breaking when un-done so you can just re-snap when ready. Just give them a good pound and they'll snap back in.
Anyone else have problems with the "nipple" that the rear washer nozzle clips to getting corroded and clogging the nozzle?
I like the no hole look, looks really clean. I need my rear wiper though. Helps in times like this to get all that damn snow off the boot.
I do believe if I ever get a clubman instead of a MCS, that I'd be doing this delete. Really makes the car look sweet.
