BMW X5 07-13 Ride Height Leveling Rear Sensor For Vehicles w/ Xenon Light (S522A) or Headlight Level Sensor
Headlight Level Sensor Failure Symptoms
Improper Headlight Beam Angle: One of the primary symptoms of a failing headlight level sensor is that the headlights may not adjust correctly. This could manifest as headlights pointing too high or too low, leading to poor visibility on the road or blinding oncoming drivers
Headlights Not Leveling: If the headlight leveling system is not functioning at all, the headlights will remain in a fixed position, regardless of changes in vehicle load or terrain. This can result in inconsistent lighting performance
