Mystery disconnected engine hoses
Discussion
Guys, was having a root around a 1.6 VW engine as shown in the photos below. The hose indicated by the red arrow has a section missing and the hose indicated by the yellow arrow is disconnected at the other end. I suspect they have been in this state for some time (at least a year 
).
So my questions are: what are these hoses, what are their purposes and what is the effect of having them disconnected as described above?
I'm sure the PH experts will have the answer! Help is much appreciated.

Its a crank case breather pipe. Carries oily gasses into the inlet track.
Having it open like that wont really do the car any halm. But it might allow unmetered air into the engine. That is air that hasnt been through the Air Mas Meter, which would make the car run a bit lean, could potentially put the emissions light on, depends how much air gets in.
Clean the oil off with brake cleaner and rap gaffer tape round it.
Looks like your secondary air pump is disconnected too. Not sure about the one with the yellow arrow, Looks like the vacuum for the servo, but you would have no brakes if that was off, so cant be, any chance of a picture that shows the other end of that one.??

Thanks Tame Technician for the reply, interesting stuff
No other pic of the yellow arrow hose but it connects to another fine hose which appears to go into the bulkhead if that helps? Reconnecting it appears to have somewhat lessened the strong smell of petrol which had been apparent in the passenger comapartment lately.
The secondary air pump was disconnected by me for access purposes.
Everything has been reconnected now but car is running a bit crappily in general; think this weekend the spark plugs will get their first change after 67,000 miles
