Bentley Publishers is the exclusive factory-authorized publisher of Volkswagen Service Manuals in the United States and Canada. In every manual we provide full factory repair procedures, specifications, tolerances, electrical wiring diagrams, and lubrication and maintenance information. Bentley manuals are the only complete, authoritative source of Volkswagen maintenance and repair information. Even if you never intend to service your car yourself, you'll find that owning a Bentley Manual will help you to discuss repairs more intelligently with your service technician. In addition to comprehensive maintenance and repair on the 1.6 and 1.7 liter engines, there's a wealth of specific information on the bigger GTI 1.8 liter engine (which includes modified fuel injection, a special cylinder head, oversize valves, and much more), the Pickup Truck (which uses a different, leaf spring rear suspension), and the Convertible's top adjustment. Complete tune-up steps and emission control specifications for the fuel-injected and carbureted engines, including the electronic ignition systems found on many models, help ensure that your car will run at peak performance.
