Touareg 2006: Replacing Parking Light Bulb in VW Torsion Bixenon Headlights with Cornering Light

I warmly welcome,
I have had a VW Touareg from 2006 for a few days. I would like a hint on how to replace the parking light bulb. The headlights are torsion bixenons, with cornering light. I took out the headlight without any problems. How do I replace this bulb? I don't have any rubber plug to get to it. I have the only rubber plugs completely on the other side and one on the bottom, but none of them gives access to this bulb. Do you have to disassemble the entire rear part of the headlamp housing, or is there a trivial way I do not notice?
Thank you in advance for the hints and best regards,
Marcin

And because of this round flap from above it will not work?

Well, it can't. Tomorrow I'll pull out the spotlight and take pictures. There is no access to this bulb. But as I say tomorrow I'll take out the reflector, take pictures and put it in here, maybe it'll help.

And the instruction manual says nothing about replacing this bulb?

Hello, case solved. The headlight is in the facelift version (black center), if someone has a similar problem, do this:
1) We take out the reflector
2) Unscrew the 4 screws on the back of the reflector, removing the cover
3) If someone has small hands, he can easily pull out the bulb (press on the holder and pull it towards you)
4) Put the new bulb in, press the socket into the headlight, tighten 4 screws
5) We put in the reflector and enjoy the replaced bulb
