hopefully you don't think I have a god complex
that's a shop floor issue and since im retired I cant score there nor do I want to ( too old for that now
) I merely state the facts from where to start from ( fault codes as you know are deceptive little buggers ) so you need to know the back ground of the systems to check what else could cause that problem ie: a vacuum pipe off will throw lots of codes because it effects the fuel/air ratio (O2 sensor/MAF/EGR/FAP etc) the list is endless when all is was is a vacuum pipe off,
just an example of things to consider ( the more fault codes you get means probably one thing is the problem ) dealers tend to throw new parts in for profit rather than a fix then blame it on something else and that's where the cost spirals hence the fear of taking your car to the dealership,
im here to prevent that and dealers don't like it because we are all smarter than they think and prefer DIY due to cost.
