How to eliminate the brake pad warning on Audi A6L?

Audi A6L brake pad warning usually indicates an issue with the braking system. The solution is to inspect the braking system and replace the brake pads. Below is relevant information about automotive brake pads: 1. Automotive brake pads, commonly known as brake linings, generally consist of two parts: an iron backing plate and friction material. Never wait until all the friction material is worn away before replacing the pads. Some vehicles are equipped with a brake pad warning system; once the wear limit is reached, the dashboard will alert the driver to replace the pads. Pads that have reached their service limit must be replaced immediately, as continuing to use them will reduce braking effectiveness and compromise driving safety. 2. Under normal circumstances, when the brake pedal is pressed, the brake light switch activates, sending current through two electromagnetic coils to the brake signal lights. At this point, the magnetic fields generated by the two coils cancel each other out, keeping the reed switch contacts open, so the warning light remains off. If one of the brake signal bulbs burns out or there is a circuit break, the faulty side's electromagnetic coil will not generate a magnetic field, while the other side's coil will. This causes the reed switch contacts to close, illuminating the warning light to alert the driver of a fault in the brake light circuit.
Resetting the brake pad replacement warning light on the Audi A6L dashboard is actually quite simple, and I've done it myself several times. First, make sure you've installed new brake pads. Then, sit in the driver's seat without pressing the brake pedal, and press the start button once to power up the instrument panel. Next, use the directional keys on the left side of the steering wheel to navigate to the 'Maintenance' menu. Scroll down until you find 'Brake Pad Replacement,' select it, and press confirm. The system will then ask if you've actually replaced the brake pads—select 'Yes' and confirm again. Finally, turn off the power and restart the car, and the warning light should be gone. However, I have a suggestion: if the light doesn't go away after two or three attempts, it might be due to a poorly connected brake pad sensor wire or a faulty sensor. In that case, it's best to visit a 4S shop to have the fault codes read with a diagnostic tool for a more reliable solution.
Last time I helped my neighbor deal with this warning alert, the process wasn't too complicated. First, turn the key to the ignition-on position without starting the engine. Use the buttons on the left side of the steering wheel to navigate to the vehicle settings menu and find the maintenance option. Select 'Brake Pad Reset,' then press and hold the OK button for more than five seconds. The dashboard will display a confirmation prompt—just press OK again. Two key points to note: First, some model years of the A6L require replacing the sensor wire for a successful reset, otherwise the warning will keep recurring. Second, avoid pressing the brake pedal during the reset process, as this can interrupt the procedure. After completing the reset, take the car for a short drive. If the warning light remains on, consider whether there might be other underlying issues with the braking system, such as a wiring short circuit.
