now, I've noticed my A6 stumbling a little when it is very cold, but
that goes away really soon after I drive off. I chaulked it up to my
MAF being bad (it is going to the dealer for replacement on the 9th).
I haven't tried pulling the codes again to see any new ones have
showed up... I probably ought to do that, huh? :)
