How to turn off the quot;check brake lining messagequot; on your BMW

1. Enter the car and leave the driver's door open. This is important, if the drivers door is not open this will not work.
2. Insert key into ignition and turn to position 2. Leave it there.
3. Hold in that position until the brake light warning message disappears. Once it disappears you can start your car and use as normal. Should the brake sensors have been installed correctly this warning message will not return. If the warning message does return it means one of 2 things. 1) The brakes are low. 2) The sensor was installed improperly, came loose, or is malfunctioning.
4. If it is still on, you can take the wheels off where the 2 sensors are located and see if the sensor is attached correctly. It goes from the top left of the wheel well (connected to a little black box) to the caliper. It is the thin black wire that you see in the picture above. Make sure that it is clipped into the caliper and connected and not damaged. If not, it is simple to change. You just remove it from the caliper and open the black box and unsnap it out. Then you can install a new one. Then repeat the top 3 steps and the warning light should go off.
