Worth a try. If possible squeeze the adjacent hose shut with a clamp to
decrease coolant lose/air entry. Have a cork or something ready to plug
the head connection. I feel that strapping tape is stronger than duct
tape; it helped me get home (300 mi) when the large hose at the front of
the engine compartment failed.
Once again note the foresight of the designers at VW, using a
specialized hose that's larger at one end than the other so that we will
buy the factory part rather than replace it with an inexpensive generic
product.
