I've been researching all day; I found confirmation in newTIS that the A21 seat memory module does control the S119 steering column, but the mirror memory isn't contained there. The A1 General module retains memory for the mirrors (the mirrors do indeed need memory, after all), and feeds data to all the affected items on my list.

As I stated before, the spare key must be used or inadvertently pressed to lower the windows and/or move the mirrors to the wrong spots, but I suspect that the A21 seat/steering control module may only need a complete reset, though the spare key also triggers it.

If I reset the A21 so my seat/steering are correct, then DO NOT use the questionable spare remote key anymore, and windows, mirrors, seats, and steering column stay where I last used them, then the A21 must be considered OK (A1, S119, A23 & A24 "door modules", too).

If the seat & steering column problems recur, using only the OEM key, then I'll start by replacing the A21 control module; if the mirrors and windows act up, then I'll look into the A1 General module. In any case, I'm buying and reprogramming two new uncut keys as remotes (only), just in case.
