There is a vacuum pump on all VW Diesel motors - right where the distributor
would be in a gasoline motor.  No vacuum = no brakes!

As does a diesel 4-speed Vanagon.  I think a more serious issue with the
automatic is that the shift points would be wrong.  A diesel has a very
different torque curve than a gasoline engine.  There's also no engine
vacuum on a diesel; I can't remember if the Vanagon automatics have a
shift modulator valve that connects to the manifold.
