Book excerpt: Everything you need to troubleshoot, service, & repair the diesel engine & its direct-cylinder fuel injection system! This manual is just as thorough as our other two Rabbit/Jetta/Scirocco/Pickup Truck service manuals, but focuses exclusively on diesel models. We eliminated information covering the gasoline engine, fuel-injection, & other subjects that don't apply to diesel engine models. Removing this potentially confusing material allows us to cover particular features of the diesel models in greater depth. You'll find testing, troubleshooting & repair steps for everything from diesel fuel injection adjustment to the oil cooler used on models with automatic transmission &/or Turbo-Diesel engines.
