What is the reason for the constant illumination of the right front turn signal on the Volkswagen Sagitar?

The reasons for the constant illumination of the right front turn signal on the Volkswagen Sagitar: damage to the turn signal lever switch, wiring damage, water ingress in the wiring, short circuit. Function of turn signals: Turn signals are controlled by electronic devices, but they still use audio to simulate the sound of a relay. They are activated when the motor vehicle is turning to alert the driver that the turn signal is flashing and to draw the attention of vehicles in front, behind, and to the sides, as well as pedestrians, as an important indicator light. Types of turn signals: They can mainly be divided into three types: resistance wire type, capacitor type, and electronic type. Among them, the resistance wire type can be further divided into hot wire type (electrothermal type) and vane type (bounce type), while the electronic type can be divided into hybrid type (with contact-type relays and electronic components) and fully electronic type (without relays).
This issue is quite common on the Volkswagen Sagitar. I believe the persistent illumination of the turn signal is mostly due to a control system malfunction. If the turn signal switch is stuck in the 'on' position, it could be caused by internal dirt or wear, continuously sending signals to the light. Another common reason is a damaged relay, which is responsible for switching the circuit; if it fails due to sticking, it will keep the light powered. It could also be a wiring issue, such as frayed wires short-circuiting to the chassis or oxidized connectors causing poor contact, allowing current to flow directly to the bulb. In this case, the light staying on not only drains the battery and affects the lifespan of the light but also misleads other drivers into thinking you're turning, increasing the risk of rear-end collisions. It's recommended to visit a professional repair shop as soon as possible to avoid minor issues turning into major losses.
