Hi, I'm writing an assignment and I'm looking for vehicle fault that's difficult to diagnose (now I want something really difficult to diagnose) - perhaps some sort of an electrical fault, an intermittent fault, a sporadic problem... but something hard to diagnose. What would be the customer complaint, and what's the best way to approach that problem? Briefly suggest different checks that I should carry out in the diagnostic process to find the fault (in the correct order) and I will elaborate on them. I'm ONLY looking for quality, be inspired.
Yeah, that sounds like a good example. What make and model was the car, and what was the customer complain? Did you get any codes when you done the diagnostics? I have to do the diagnostics on paper in a logical sequence (I can't say that I start replacing parts) LOL. I need more detail about previous checks, P Codes, perhaps what live parameters would you expect and what would you look at, and some more details about the problem will help me elaborate on the rest and pull it together. Thanks!
Great! One last thing. You said it was an Audi S4, with a V8 engine. Do you remember the year and when did the fault first occurred? was it after the customer serviced it at 80k miles or some time after that?
