Used this way it indicates that the person knows much more than the backyard mechanic and is showing so but giving his advice then offhandedly tossing out his status as a proffesional.
Once and a while during a thread someone has offered lengthy words on how they're oppinion is the right and true oppinion ( or something to that effect ) and then tried to "dumb it down" by saying " but I'm just an Auld Crabbit". People reading the thread know that the author is coming from a level of authority ( warrented or supposed is another matter ) and it's obvious that the advice, critique, or what have you is meant in all seriousness. When the author ends with " But I'm just and Auld Crabbit" They are implying that they are in the know and their words should be taken with utmost seriousness.

Now of course there are times and I think it is most of the time that the title is tossed out there just in fun. I am simply pointing out that every once and a while it is not and maybe that is where the OP is coming from.
This is exactly what I was looking for!!!
Ok it makes more sence to me now. Let me repeat it to make sure I hit it.

A trusted mechanic tell his client "my opinion is your cv joint is about to give out. That's why it's knocking "
The client says " I had a car before that made the same noise. I think it's the motor mount"
The mechanic in frustration says "your right. What do I know? I'm just a idiot with a wrench." knowing full well he is a serious mechanic and his comment should be taken as sarcasm.
