About fault-finding
It's about finding the right problem, not just the first symptom
Fault-finding is the part of workshop work where the car is examined systematically, so you're not just reacting to symptoms but actually finding the cause. That can be anything from a check engine light, to uneven running, starting problems, or loss of power under load.
A proper car diagnosis leads to better decisions. When the problem is found correctly, you often save both time and money, because parts aren't swapped on a hunch. It also makes for a much more reassuring process, because you know what's wrong and what the next step should be.
