My crankcase breather hose (i think it's called that) is broken, and now I wonder if this is something I can fix myself (to a new hose). The topmost end seems simple enough but where is the other end and how do I reach it, I think it looks like it goes somewhere under the engine.

By the way: the car is an Octavia Combi 1.6 -03

Very common on the 1.6.

The hose comes up from the oil filter housing at the front of the engine, up to the oil filler cap and then onto the inlet pipe. You can get each part individually.
