I agree that both Bentley and Haynes are complimentary.  I also have the
"Vanagon Workshop Manual"
http://www.busdepot.com/details.jsp?partnumber=VW82WH  I usually read
them all for the procedure that I am about to attempt because they all
have some information/tips to offer.  E.g. the Haynes says the coolant
bleed valve spigot on 1.9 are fragile and to be careful when removing
the coolant hose from it.  I read that after I broke mine removing the
hose ;o(

 

To my knowledge those are the only three manuals available.  The other
source of invaluable information is the net.  The network of altruistic
Vanagon & Westy owners willing to post procedures and provide advice is
truly amazing, and invaluable.
