What is the reason for the lack of reverse camera display when the Volkswagen Sagitar is in R gear?

The reason for the lack of reverse camera display when the Volkswagen Sagitar is in R gear is due to poor contact of the reverse camera switch. The Sagitar is a compact car model under the Volkswagen brand. Taking the 2018 Sagitar as an example, its body dimensions are: length 4753mm, width 1800mm, height 1462mm, with a wheelbase of 2731mm and a fuel tank capacity of 50 liters. The 2018 Sagitar features a MacPherson independent front suspension and a multi-link independent rear suspension. It is equipped with a 1.2L turbocharged engine, delivering a maximum horsepower of 116PS, a maximum power of 85kW, and a maximum torque of 175Nm, paired with a 5-speed manual transmission.
I heard experienced drivers discussing this issue in the car owners' group last time, saying it's quite common for the Sagitar to have no reverse camera display. First, check if the camera lens is dirty or covered with mud - I once found mud splashes on the camera after car washing. Then verify whether the parking sensors are also malfunctioning; if the sensors work normally, then it's an isolated issue with the camera system. The wiring harness in the trunk area undergoes repeated bending during opening/closing, and connector loosening is very common over time - I've personally experienced poor contact in the trunk wiring. If the infotainment screen freezes, it may also cause the camera display to fail - try holding the restart button for ten seconds. Additionally, if the ACC power line was incorrectly connected during aftermarket reverse camera installation, the system might misjudge gear signals - this requires revisiting the modification shop to check wiring. Finally, don't forget to inspect the head unit settings, as software updates sometimes mistakenly disable the parking assist function.
As a female owner who has driven a Sagitar for ten years, I've personally encountered the reversing camera disappearing twice. The first time was because the aftermarket dashcam interfered with the reversing signal transmission line, and removing the dashcam immediately fixed the issue. The second time was even more frustrating—after a maintenance service at the 4S shop, the technician didn't securely plug in the trunk wiring harness connector, and it got loose from the vibration over speed bumps. Common causes for a black screen on the Sagitar's reversing camera usually include: the camera lens being blocked by snow or bird droppings, damaged wiring from pulling the cable when opening the trunk lid, system lag in the multimedia host requiring a factory reset, or short circuits caused by moisture intrusion on the circuit board during rainy days. If it's a new car still under warranty, it's best to take it directly to the 4S shop for a claim. For older cars where inspection costs are high, installing a small convex mirror to assist with reversing might be a more practical solution.
