How to get out this plastic screw fastner?

Turning it does not get it out. I can reach around to the back and I can feel some plastic indentations, is this a type where to get it out I need to somehow release the clamps from behind? Do I need any special tools?

It's a screw that holds the engine underside plastic cover and I need to get rid of it to do my oil change and access the filter/plug

Video not working. If its plastic just cut it and replace it with a new one. Buy the new one first.

1999 has the right idea. People waste to much time on this. Force it out and replace it. In a pinch use a self tapping (sheet metal) screw .

The plug is two pieces. The outer plug spreads when the small screw is inserted. It's like a plastic drywall anchor. Reach behind and tightly hold the outside of the plastic plug. Unscrew the inner plastic screw

My Mini has a bunch of these things. When you have access to the back, hold the prongs tightly and unscrew. It should pop right out. When you don't have access to the back, you need two screwdrivers (a flat head and a Phillips head). You hold the outer ring down tight with the flat head ( or some needle nose pliers) and unscrew with the Phillips. Don't be tempted to use the wrong size Phillips as you'll surely strip the screw (soft plastic) In the case where you do strip it (and eventually you will), you can heat up the tip of the screwdriver and melt yourself a new +. I always have a bag of these lying around. 95% of Mini Cooper front end repairs involve removing at least 10 of these fasteners.

I usually wedge a pick between the two parts and unscrew it. If it's still spinning /stripping the head, use a pick/small screwdriver to wedge between the two parts and use a small pry tool to lift the top clip.

Use your fingernail or a flathead screw driver to press down on the outer ring part while also lifting up as you spin the inner part with a philips head.

Most of the time you can just pop the centre piece out with a flat head but there are some that you have to spin with the above method.

Either pinch the back to unscrew or try unscrewing while pulling the piece your trying to remove, point is you need to create tension behind the plug.

If its a soft plug, you can probably just push the screw out
