bmwman528e Those 214s look so good! I couldn't afford new so would have to get reps and even that would cost plenty to get over here :-/
Anyways, used the E53 to drive to get Torx sockets to do, you guessed it, the xfr case actuator gear! But for the X3, am posting victory pic here because that forum is so dead. Plus found out about it here anyways (thank you posters). Got a spare gear (same p/n) for the E53 and holding off if/until get the triple.
All error lights gone now and hopefully for a long long time - yay!
