The causes of electrical failure in the Touareg electronic parking brake control unit: 1. The parking brake is not fully released: You can pull the parking brake and release it again to see if the light goes off. 2. Brake fluid leakage: You can go to a repair shop or 4S store to check and fix the brake fluid leakage, then replenish the brake fluid, and these two lights will turn off and return to normal. 3. Worn brake pads: This causes the brake fluid level in the reservoir to drop. When the level drops to the point where the sensor is activated, the parking brake light will illuminate. However, if the fluid level is just at the threshold of activation, the light may flicker on and off as the vehicle moves. Therefore, first check the brake fluid level by opening the hood and inspecting the brake fluid reservoir, which has marked levels. If the brake fluid is indeed too low, you should check whether the brake pads have worn to their limit.
