Push pin clips in wheel arches

The wheel arches has a one time clip that you have to drill out, if you want to remove the bumper or the plastic arch.

When putting the parts together again, the push pin clips are very useful here. You just have to use an 8 mm drill to make the wholes a bit larger. These clips are cheap on Ebay, and you can use them over and over again.

This is especially useful on later models, where you have to partly disassemble the bumper to get to the right headlight. You have to take out this headlight to change some of the bulbs on the headlight assembly.
