Five Ws of Diagnostics
We have already discussed intermittent electrical problems. As a follow up, we want to mention something that may assist in the analysis of your BMW’s problem.
Think of it as the “who, what, where, when and why,” of the symptom. One example as follows;
“My son was driving the BMW, and now we have an indicator light on. It happened after he filled the tank, (wishful thinking that we have someone else, filling the tank, these days)!”
See, you fill in the “who”, “what” and the “where and when”, and we will advise you (after the diagnosis), of the “why”. Try to remember the specifics surrounding the situation. (The above example is an easy one for us, but you get the picture).
This information will get us on the path to analyzing your problem, using the equipment and knowledge that we have gained. After all, we have over 150 years of collective experience in BMW here. (No geezer comments, please).
A good Service Advisor will be asking questions and really get the dialog going. This is just part of the effort to get to the heart of the problem. Great communication is the start of great customer service.
