What Causes the Black Screen in BMW's Rearview Camera?
2 Answers
BMW's rearview camera black screen issue is caused by poor line contact. It is necessary to promptly check the wiring and the connection points installed in the vehicle to see if there is any loose connection. If there is, it will naturally lead to intermittent functionality of the rearview camera, and even a complete black screen is possible. The BMW 3 Series has a body length, width, and height of 4719mm, 1827mm, and 1459mm respectively, with a wheelbase of 2851mm. It features a front-engine, rear-wheel-drive layout, equipped with a 2.0T turbocharged engine paired with an 8-speed automatic transmission. This engine delivers a maximum power of 115kW and a maximum torque of 250Nm.
I was really freaked out when the reversing camera on my old BMW went black. I guessed the lens might be covered in mud since the car was filthy after that off-road trip. When reversing, nothing showed up on the screen. Luckily, I tried wiping the lens by hand, but when that didn’t work, I went straight to get it fixed. The mechanic said it could be a loose or oxidized wiring connector, or maybe a blown fuse—older cars tend to have electrical issues. He recommended regularly checking the camera area for cleanliness to prevent rainwater from corroding the connectors. If the screen goes black, it’s best not to reverse too far to avoid hitting something; using mirrors or getting out to check is safer. After that repair, I learned to inspect it before every drive. It cost me over 300 yuan, but it went smoothly. Paying extra attention during routine maintenance can prevent a lot of trouble.
