Assuming that the sensors are fine, you'll probably need to disconnect then reconnect them to trick the car into thinking they were replaced. I've yet to do a brake job on a bimmer due to mileage, so I've never had to confirm this myself, just an educated guess.
If this doesn't work, the old trick is to cut the sensor off (since it's just a piece of metal that will wear down, when its worn to a certain point, the connection breaks meaning no electricity flows through the sensor). Remove some of the sheathing and connect the two wires together, then solder them/heat shrink over to prevent the elements from getting to em. There will be a DIY either here or on E90 post.
The alternate approach would be through coding, see the below threads, PM me if you need help with this route.
