I never have any intentions to ignore input or defend something just because. I have no problem admitting when I am wrong. And, in this case, I am wrong about how the system works. I do stand by the poor man's methods of troubleshooting.

I agree that we are more knowledgable about some aspects of a vehicle than others and certainly there are differences in how things work from one brand to another so it is never a good idea to universally apply how things work. In my case I was thinking only of an E53 because that is forum.

JFOJ, Regardless of certification, experience or day job, I think when one declares themselves an expert they begin to be less effective. I suggest you use your knowledge to respectfully explain how something works when someone disagrees without sarcasm. I can't compare this forum to others but I do know OPs get help here. The forum was doing fine before I joined and it will do fine when I am no longer a member--none of us are an exception.
