I know there are a load of questions on this, still can't find the exact answer.... So,
I am seriously thinking of getting one of these tools, I know my way round cars, motors, electrical etc, I fix aircraft for a living.
I've got a BMW cd manual on the way.
What I'd like to know, simply, does this tool, pin a code to an actual component...
I've got a fuel problem on my 330d, I'm fairly sure its fuel pressure related.
Would an example code be...
'SO12 fuel pressure' .... (random example) leaving me to test all the components in the system to find the faulty one.
or will it be
'SO12 fuel pressure, check fuel pressure regulator pn22' (random example)? thereby narrowing it down to a component level?
