Can I continue driving if the ABS sensor of the Tiguan fails?

[SanDamian]

ABS warning light is on, it is recommended not to continue driving, because the ABS light on means that the vehicle's anti-lock braking system has failed. In case of emergency braking, if the wheels lock up, the vehicle will lose control and skid, making it impossible for the driver to slow down or adjust the vehicle's trajectory, which poses a significant safety hazard. There are various states of the ABS light being on, and the causes and solutions for different states vary. The details are as follows: State 1: ABS warning light stays on (most common). Cause 1: The sensing part of the ABS speed sensor is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. As a result, the ABS computer cannot determine the speed or the wheel's slip rate, and thus cannot issue appropriate commands to adjust braking. Solution: Clean the dirt on the speed sensor and adjust the gap between the speed sensor and the signal ring to restore normal function. Cause 2: Poor signal due to loose connections between system lines or poor contact of the ABS relay, leading to system failure. Solution: Check the line connections and reconnect any loose parts. State 2: ABS warning light intermittently lights up and turns off when accelerating. Cause: When multiple vehicle electrical devices are used, the battery voltage drops below 10.5V. As the engine speed increases, the voltage rises, and the ABS indicator light turns off; the ABS system power supply voltage is too low, such as poor contact at the terminals or grounding. Solution: Check the battery's specific gravity; inspect the charging system; check the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light stays on after the engine starts and only turns off when the engine is turned off. Cause: Poor contact in the ABS hydraulic valve body's grounding circuit; poor contact in the ABS hydraulic valve body's wiring connector; ABS computer failure. Solution: Loosen the grounding screw of the hydraulic valve body, then tighten it again, cleaning the contact surface if necessary; check if the connector gap has increased; replace the ABS or ABS/ASR computer. State 4: ABS warning light turns on during high-speed driving. Cause: During high-speed driving, the ABS computer detects a significant difference between the rear and front wheel speeds; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: ABS warning light intermittently lights up. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: Start the engine, press the brake pedal, push the brake switch linkage down to the bottom with your fingers, then release the brake pedal to complete the self-setting position; replace the brake light switch.
