I guess I have the DA-6. The thing that puzzles me is that it
only works in the "push in and twist" timer mode.  I can't get
it to work on just the twist mode that is suppose to be
available with the ignition on. Anyone have a clue?

Eric,
VW installed two types of heaters for the Vanagon, the booster
which was for
80-83 air- cooled Vanagons, and the auxiliary for water-cooled
84 - 91. It is
called the BA-6. 82-83 Diesel Vanagons had the DA-6, same as the
BA but uses
Diesel.  The BA-6 will not fit in a Synchro.  The BA-6 was
introduced in 1975
in the Type ll to '79. The Vanagon BA-6 to 83 is the same as the
Type ll
BA-6. The 84-91 BA-6 auxiliary heater utilizes two fuel pumps,
the booster
one.
 The BN-4 is a pre-75 heater that came as optional equipment in
1968 for Type
ll.  For the Synchro model there was a Canadian only optional
heater booster
called the BBW 46 which heats the engine coolant. Something
similar to this
is still available by Eberspacher called the BW4 Hydronic. They
also make a
air heater as compact as the old BN-4 called the B1LC.This month
I am
installing a BN -4 in a Synchro.  If you are interested I will
let you know
how the installation goes. I also have several of the BN-4's in
stock. The
most economical heater for the Synchro is the BN-4. The new
Eberspacher
models are over 800.00.
