What are the reasons for the missing rearview camera in the Sagitar?

The reasons for the missing rearview camera in the Sagitar are: 1. The camera is damaged or blocked by something; 2. Poor wire contact; 3. The battery is dead. Taking the 2018 Sagitar as an example, it is a compact car with body dimensions of: length 4753mm, width 1800mm, height 1462mm, a wheelbase of 2731mm, and a fuel tank capacity of 50l. The 2018 Sagitar features a front MacPherson independent suspension and a rear multi-link independent suspension. It is equipped with a 1.2L turbocharged engine with a maximum horsepower of 116ps, a maximum power of 85kw, and a maximum torque of 175nm, paired with a 5-speed manual transmission.
I just encountered this issue last month - the black screen on the Sagitar's reversing camera was terrifying. The most likely cause is mud covering the camera lens; closing the trunk after rain can splash mud onto it. If cleaning doesn't help, there's an 80% chance the small fisheye camera at the rear is faulty. Volkswagen's camera placement near the exhaust pipe makes it prone to moisture buildup during winter's temperature fluctuations. Also, repeated trunk lid openings can snap the wiring harness - a common issue I see during repairs. By the way, a frozen infotainment screen can also cause black screen - try holding the volume button for 10 seconds to reboot the system. If the parking sensors beep but there's no image, the easiest solution is visiting a dealership to read the fault codes.
This issue can be analyzed from several key points. The camera itself has the highest probability of damage, especially in older vehicles where the lens may be blurry or fogged up; loose wiring connectors are also common, with the wiring harness at the trunk hinge being prone to poor contact due to repeated bending; a crash in the infotainment system can occupy the video channel; a blown fuse is more straightforward—check the location of the reverse camera fuse in the manual, usually labeled F36. Last time I helped a neighbor troubleshoot, it was a short circuit in the license plate light that also took out the camera system. For modified vehicles, consider potential wiring interference, as aftermarket cameras may not match the original factory protocol. Before diving in, try unplugging and reconnecting the trunk wiring harness first.
