I have the 041A for $9 too and they are VDO but here is the catch.  The
syncros I have seen (which is only a couple) have had a aluminum or some type
of metal bottom to the thermostat housing.  Into this housing you can only
screw in the earlier sender (041).  I actually have these for $30 (cheaper
than I remembered) and they fit the syncro and the 1.9l Vanagon.  Check your
van.  Do all syncros have the metal bottom of the thermostat housing?  I just
assumed so since all the ones I saw had them and I figured they did this to
make them stronger and more rock resistant.  So if you have the plastic
thermostat housing the 041A will work, but the metal folks out there need the
041.

Thanks,
