A phrase that I often hear from customers is, "This is a diesel engine; the problem should be easy to diagnose." The right part about that statement is that the customer realizes that he has a diesel engine; the wrong thing is the assumption that it is easy to diagnose. Certainly, there's some common repairs needed on specific engines that are easy to do but doesn't mean that it makes everything else easy to diagnose. Owners often think that because diesel engines are now electronic the technician should be able to hook up a scan tool and immediately see what is going on.
