Subject:      update on syncro coolant distribution unit

I think I finally have some resolution on the problem I've been having
getting the proper coolant distribution unit part for my syncro (see
description of problem below). Apparently VW has superceded the old part
with a new part that has an extra hole in it that requires a plug. Camelback
VW has tracked this down for me and is sending the plug (three pieces
actually). I'll post the part numbers to the list as soon as I receive them.
My guess is that they added the plug to facilitate draining the cooling
system. Sounds like a bad idea to me--just something else to leak. The plug
is not shown on the dealers' fiche and several other dealers and their
service managers were not aware of this part change. Syncronauts
beware--this piece does fail sometimes and will be probably be difficult to
obtain on short order.

I recently said:
