i just pulled out a weird piece of rubber that was sticking out on the side of the drivers window, it was like right in the middle of the window
its dark green and it has thins thing sticking out that looks like it would plug into something
will add some pics latter

 

pics are generally a good idea BEFORE u post a thread asking what something is

 

sry for the quality of the pics but i have a crappy camera that cant really do macro

holy ****... does it not know what focus is? my eyes hurt... but that looked more blue than green

 

yeah it looks green when i look at it in my room cuz its kinda dark but the color doesnt really matter :P i just wona make sure that i wont get my window scratched when i put it down now or something? maybe this is some kinda of protection for that? who knows ^^

 

Well, if it came from within the window, chances are it pertains to a function of the window. Maybe water shielding for electrical connections? My first instinct is that its a plasitc foot for the bottom corner of your window's glass.
Take the afternoon to throughly get aquainted with your window's control mechanisms. Its like the good old days, find the differences between the ripped open door panels.

 

I've had at least one of those come off on every A4 i've tinted, there not important at all, If I remember correctly they dont actually touch or protect the glass at all. they just clip into the black metal piece that the top of the door panel sits on.
