Dear Vanagon Enthusiast:

I am having a problem with the computer on my 1984 vanagon (Bosch 0 280 000
501).  I would like to repair it myself, since I can not afford to buy
another one.  Therefore I need to obtain the circuit diagrams for the unit
and preferably a parts list so I may be able to buy the parts in any
electronic store.  Could you please help?

A prompt response is greatly appreciated.  Thank You.

Sincerely, Genaro Calderon.
