Likely you got to this Repair Database section from a link in Service & Repairs. When you are tab browsing, it may look like the same repair appears in Knowledgebase. Well, yes it does, and the name may appear more or less the same. But the Service & Repairs section is more of a customer oriented synopsis about the basic maintenance and repair necessities. The Knowledgebase is more about How Stuff Werx and What Breaks, and a synopsis plus explanation. This section is called the Repair Database. Think of it as another road map of your car.
