Where  was the BBW46 installed?   Was it under the rear bench on the
passenger side?

In the Hyena (our 1988 WBX Westfalia), I have a gas  heater which does not
work - the fan comes on, but no heat.  It has the  green-knobed manual timer
in the dash just below the heater controls like that  which was present in
our old 1972 Westfalia.

However the heater itself  appears to contained under the drivers side of
the van above/in a large metal  shield/encasement which looks like an
oversized catalytic converter.

I  did not have time to dig into it last summer, but when I take the Hyena
out of  storage this spring, I'd like to attempt to get it  working.

the gas fueled coolant preheater - webasto BBW46-  was installed in  the
engine compartment.  it had a little digital control readout mounted  under
the dash this coolant preheater was an option on waterboxer vanagons in
canada.

what your describing on your '88 westy,sounds like it is indeed a
Eberspacher BA6.   can you install a Eberspacher BA6 on a waterboxer  vanagon? Sure
you can.  ive sold them to people who have done it and have  one here that i
plan to install in my '89 westy (someday) You just do some  custom ductwork
and it will work fine.   Did volkswagen install the  Eberspacher BA6 in
waterboxer vanagons from the factory?   not to my  knowledge..  but your in
canada, so it may be different up there.   does the installation look factory,
or custom?    you describe  the heater unit as being mounted under the
drivers side of your vanagon -  volkswagen mounted them under the CENTER of the
vanagon.. behind the gas  tank.  not on the drivers side.
