thanks for the info... that make sense -- it was just into the dealer for its last "free service" (they originally gave me a 'basic maintenance' package when I bought it), so they must have forgotten to reset it... It was weird, because the oil was literally *just* changed and it's even still clear... but I guess that indicator is just showing that they didn't reset it.

It's disconcerting, though, that B0100 is so different on different scanners and different cars... How were you able to figure out that's what it was? (did you look it up somewhere?)

Thanks again,
Bob
