Thanks for replying, Gilly!
Ok, I have found a reputable, independent European import repair shop, and I spoke with the owner
at length today. My car is going in on Thursday... he is going to hook it up to the SDS (yay!) reader and see what he may see. His estimate is one hour, and he will call me if it needs more.
I am optimistic that it will be only an hour.

Wagers? LOL
So, I'll post results Thursday...
