Why does the BMW X3 reversing camera suddenly stop displaying?
2 Answers
BMW X3 reversing camera suddenly stops displaying may be due to poor line contact causing a circuit break. Need to check whether the line is damaged: Check whether there is a loose connection at the wiring installation of the whole vehicle, or whether the video power line has aged. If there is a problem with the line, it will cause the reversing camera to malfunction. Just reconnect the loose part of the line or replace it with a new power line. The camera has been used for too long: It may be that the reversing camera has been used for too long, causing the chip's light-sensing effect to deteriorate, resulting in a lot of snowflake phenomena, and in severe cases, a black screen. The display screen is damaged: When the display screen remains black and cannot start or shows a mosaic problem, it generally means it is broken and needs to be replaced. If the chip is abnormal or the display screen is damaged, it needs to be inspected and repaired at a repair shop or directly replaced.
I just encountered the issue of a black screen on the BMW X3's reversing camera last week and spent quite some time figuring it out. The most common causes are the camera being covered in mud or dirt, or the connection wires getting loose from frequent trunk openings. Another possibility is the infotainment system freezing—try holding the volume button for 30 seconds to force a reboot. If you've recently modified any components, it could be due to wiring conflicts. A blown fuse is also a potential culprit—check the F57 position in the fuse box on the left side of the trunk. In humid weather, oxidized wiring connectors can cause this issue too; try drying the connectors with a hairdryer. If all else fails, you’ll need to visit a dealership to diagnose the fault codes with a scanner. Repairing the BMW camera module isn’t cheap, but for parking safety, it’s not worth toughing it out.
