Had an issue with my sunroof (electric) where it would go up and down but not slide back at all. on inspection I found this was trapped under the runner so pulled it and everything working fine. Question is it a part that's broken of. just a black pipe It's only bent because of me pulling it out

Possibly a drain pipe,connected to the frame to get rid of water,may need to drop roof lining to refit,but no idea if it's at the front or back.

Can you put something beside it and take the photo again, because it’s very hard to get any idea of scale from that picture
