I'm replacing my electric windows which were an electric life kit with a genuine VAG set and I've met a problem. One of the holes that the new regulator and motor needs to go through has a threaded thing (sorry, only way I can describe it) which one of the bolts from the old setup went through.
This threaded thing is obviously preventing me from putting the new mechanism in and needs removing but I can't figure out for the life of me how to get it off.
Here are some photos of the offending article.


Apologies for my sh!tty camera work.
Can anyone shed some light on it?
