From the thread linked above:
"The pads are easy to change, but unfortunately BMW has made this a non DIY project. The reason is you used to be able to push your pistons in on the floating rear caliper, drop your pads in and go. Now the G body cars have calipers that have to be retracted with a computer. If you don't, your dash will light up with errors and alerts. I have a friend that has the software to retract the rotors for me so I did the job myself."

"I was told this started in all the G chassis cars. I’m not talking about the pad wear sensor that clips into the top of the pad. There’s something in the caliper that tracks the pistons position within the caliper. When you manually move the piston, the car gets confused on the position of the piston and lights up your dash. You can manually move the positions, but there is a chance for damage BMW says, and then go to the dealership and have everything reset. I imagine they’ll charge you an hour of labor. Just keep in mind the car may not brake properly if it’s confused on the pistons position."
Read further down that thread. Some have tried it without software by following instructions from the tis info.
