What causes the ABS warning light to illuminate in Volkswagen vehicles?
1 Answers
The reasons for the ABS warning light illuminating in Volkswagen vehicles are: 1. Low battery voltage or blown fuse; 2. Broken ABS system wiring, loose connectors, or improperly seated relays; 3. Faulty wheel speed sensors; 4. Malfunctioning hydraulic control unit; 5. Defective electronic control unit. When the ABS warning light comes on, it indicates a fault in the ABS system, causing the system to deactivate. This means the vehicle operates as if it doesn't have ABS, resulting in reduced braking performance (longer stopping distances, poorer handling during braking, etc.). Therefore, the fault should be addressed promptly when the ABS light illuminates. Taking the Volkswagen Lavida 1.5L manual base model as an example, it is equipped with a 1.5L L4 engine and 5-speed manual transmission, featuring naturally aspirated intake.
