E83 Bmw Bumper How To Replace The Headlamp Washer Cover Cap On A BMW X3 (E83)?

How to replace the headlamp washer cover cap on a BMW X3 (E83)? - e83 bmw bumper

I have a 3.0d BMW X3 (E83) with M aerodynamic body kit that has retractable headlight cleaning system - they are automatically activated every time you fifth of the wiper. The cover is a color code coverage on the front bumper (not part of BMW. 61.67.3.416.176) - One of these drivers and ordered a replacement from my dealer. Now, the party came, I'm not sure how to adjust. Looks like I start the cleaning, catch pop up and try to have to cut the cover up? Any advice would be welcome to avoid, breaking my car and / or a fortune in the bank to do it for me!
