Bob,

Aren't you supposed to set it to 10-12 degrees BTDC?

I haven't set mine but I will be doing so tonight.  If your engine is of
the same or similar batch as mine it probably came with NGK plugs and
those 'silicon' wires.  I don't like either of those so I would be
swapping that stuff to genuine Bosch if the ignition continues to give
you trouble.  (That's what I'm going to do if I don't like the feel of
things once I have the basic params setup on the engine.)

Good luck and keep in touch on it - I'll let you know how mine works out
tonight.  (I just got my VAG-COM software and cable so I can interface
my laptop with the motronic computer...)
