John--

Check the wiring diagram for conections between the ignition switch and the
distributor, or associated circuits/relays. Since your ignition switch is new,
it *may* not have all of its leads seated correctly, and one or more may be
making only intermittant contact. This would explain the timing of the Hall
sendor "failure" and the multiple keystrokes to start.

If this isn't the answer, yes, take it to the dealer. They will find the
problem faster than you can say "Vanagon Carat Westfalia Synchro Deluxe, with
hood scoop and curb feelers".

<< I recently posted this question about difficult starting of my 91 Vanagon.
 One out of 10-15 times the engine would crank about twice as long as normal
 before starting.  My mechanic had found that the voltage in the Hall
 sending unit was dropping to about .2 volts when this happened but couldn't
 figure out why.

 Well......, we replaced the Hall sending unit (new) and now the difficult
 start  is almost a constant problem.  It either cranks and starts when you
 turn the key or you have to crank it once, stop, then do it again - maybe 3
 or 4 times before the engine will start.  This isn't doing my new starter
 any good I'm sure!  Ignition switch is new too.

 So?  Could the new Hall sending unit be faulty?  Would it be the
 distributor?  Possibly a computer problem?  Can any of these be tested
 without replacing  them?  Should I go to the VW dealer
 (Aaaaaaarrghhhhhhhhhhhh)? >>
