What's the reason for BMW X4's non-responsive reverse radar and central control?

It is highly likely due to poor line contact. It is necessary to promptly check the wiring and the connection points of the entire vehicle's installation to see if there are any loose connections. The following are other possible causes: Aging of the video power cable: You can try replacing it with a new power cable. If the issue is resolved, it indeed indicates a problem with the video power cable. Prolonged use of the car camera: Extended use of the car camera can lead to poor chip photosensitivity, resulting not only in a snowy screen but also potential black screen issues. Such chip abnormalities and design defects are beyond the owner's ability to resolve and require inspection, repair, or direct replacement at a repair shop.
My experience tells me that the simultaneous malfunction of the BMW X4's reversing radar and central control is most likely due to an integrated system issue, such as the central control module freezing or failing, as modern cars often bundle these functions together. It could also be a power supply problem, like a blown fuse or unstable battery voltage causing an interruption in the circuit power. Dirty sensors can also affect radar signals. Software glitches are quite common, and BMW's new systems are prone to freezing. I recommend doing a simple check first to see if anything in the fuse box is burnt out, then try a power reset by turning off the vehicle for a few minutes before restarting to see if it returns to normal. If this doesn’t work, don’t delay—seek professional repair immediately, as driving safety could be compromised. Such faults aren’t uncommon in luxury cars, but extra attention should be paid to maintenance, as aging wiring can worsen the issue.
