4 Series Scania curtain rail replacement

Hi all,

How do I replace the front section of the curtain rail on my 2011 Sacnia?
It looks like a rat has been chewing on the corners on both sides and the curtains won’t come round to the front of the window, so before I make a mess of it and breaking all the clips I thought some of you guys could post a you tube link or give me a simple descripton on how to remove & replace the rail.

Any useful info will be greatly appreciated.

By the way the rat that chewed it was a 2 legged one!

just screwed on isnt it? and that would be an r series 2011 not a 4 series :grimacing:
