If the pipes been broke off for a considerable time dirt and damp may have entered the system, you could either replace the broken pipe or it may be repairable.
This will enable the system to be vacuumed and pressure tested and if OK then regassed but don't be surprised if there are other leaks especially the condenser/dryer as this is quite common.

That's a chance you'll have to take if you want any chance of it working, Iv'e had two pipes and the condenser dryer go on my MK2 all at different times and of course that's a regas every time, it can be an expensive time but has been good now for four years
