my run around engine bay looks alot worse, but until it stops working, no need to change it!

the pipe thats broken is called the crank case breather pipe, couple quid from vw or if you look around a couple breakers might have one for cheaper, best bet is go to your local VW and get them to give you the part numbers on an estimate sheet, if its cheap enough, get it from them, if not, at least you have part numbers to search the internet with
not that difficult to change, by the looks of the picture a set of screw drivers should do for you, just make sure you remove any broken bits as they are not good for the internals of the engine!
