Bentley manual

The Volkswagen Vanagon Official Factory Repair Manual (ISBN: 978-083760336-0) by Bentley Publishers is commonly referred to as the "Bentley" or "Bentley Manual". It was last updated in July 1991, and is roughly the best $70 USD that a Vanagon owner can spend.

The Bentley includes diagnostic, maintenance, and repair information for many subsystems of the van.
