What is the problem if the door of Volkswagen Sagitar cannot be locked while driving?

First, check whether the locking device is working. If it is not working, it is likely caused by poor contact of the central control system wiring. If it is working: Then it may be due to high resistance in the locking mechanism, which is usually caused by rust; or it could be that the position of the door lock motor latch has shifted, which only requires adjustment at a repair shop. Another possible reason is that the door lock motor is damaged and lacks sufficient pulling force, in which case the motor needs to be replaced. Short circuit in the locking device wiring: If no sound is heard, it indicates that the door lock's locking device is damaged or there is a short circuit (open circuit) in the wiring harness, requiring replacement of the locking device and inspection of the circuit.
I've worked on many Volkswagen Sagitars, and doors not locking while driving is usually due to issues with the door lock mechanism. For instance, the door lock actuator might be worn out or stuck, especially in older vehicles, preventing it from receiving the locking signal. The central locking system is crucial—any malfunction here affects all door locks. From cases I've seen, poor plug connections or wiring shorts can also cause this. Start with basic checks, like ensuring doors are fully closed, as faulty sensor readings can block locking. Some Sagitar models have design flaws making door lock modules prone to overheating failure; a diagnostic scan is advised to pinpoint the issue. Don't ignore it—unintended door openings while driving are hazardous. Address it promptly by replacing actuators or applying lubrication; it's better than letting it escalate into major repairs.
