I had all the same errors from bad voltage regulation. If trans goes into limp mode you get gears 3&4 that's it.

Make sure you have 13+ volts and engage parking brake and turn engine off and on a couple times to reset trans.

Speed sensor is hermetically sealed its life is always going to be one of gunk but if it's wacked it will trifecta your dash lights : brake, dsc, abs. (But also voltage dip below 12v will trifecta the dsc). If brake is yellow that's most likely a sensor or voltage blip. If brake is red than low brake fluid (ask me how I know)

I've seen a couple ways to remove the bearing and for diy the easier way is to remove the cv axle from the differential so you don't have to deal with the spring (air bag) pressure which normally is dealt with using an additional jack.

I think it may be possible to get to the e-torx using a couple flex adapters rather than removing cv or dropping the suspension.

Im going to be replacing rear bearing on my wife's x5 within a week or so I will post my solution if I figure out an improved method.

Thanks for the head up on the slide hammer difficulty. I think I will use the method I used for the front bearing an push the bearing apart using some long bolts through the lug holes.

For re installing I've beefed up my bearing press that used to self destruct. Had a 3/4 " threaded rod good for 23,000# but apparently it takes 30-40,000# to press front x5 bearing so I now have grade 8 1" bolts good for 62,000#
