Audi Q5 reporting a high-mounted brake light malfunction may be due to three reasons: brake light switch, wiring, or the brake light itself. Below are the specific details: Brake Light Switch and Wiring: If the brake light malfunction has been ruled out, then it might be due to a faulty brake light switch or wiring. Wiring Fault: If the brake lights on both sides are functioning but the high-mounted brake light is not, and the brake light switch is working normally, then the issue is likely a wiring fault. Multimeter Testing: Use a test light or multimeter to check the brake circuit on the brake light's high line. If a break in the wiring is found, it can be repaired. This requires professional repair personnel to fix.

How to Clear the Yellow Engine Light on a Skoda?

When there are no obvious abnormalities in the engine's operation, you can try restarting the engine to clear the fault light. If you are certain there are no issues with the engine's operation, you can attempt to clear the fault code by disconnecting the power or removing the fuse. Another common cause of the fault light is a malfunction in the front or rear oxygen sensors. Checking these components usually resolves the issue. For more severe faults, such as the vehicle breaking down, it is necessary to visit a 4S shop to diagnose and repair the engine fault using the fault code.

How to Remove and Install a Skoda Steering Wheel?

The steering wheel is quite easy to remove. Use a mirror to look at the back of the steering wheel, press down with a small screwdriver, and the airbag clips will pop out on their own. The three clips can be removed in seconds. Pay attention to the airbag wiring harness. First, pull the white lock outward, then pinch the yellow connector and pull it outward with force. After removing the airbag, you'll see the V-shaped metal rod—the airbag clips are fastened onto it. For the original car's airbag wiring harness, remove one and replace one to avoid mistakes. To remove the steering wheel, use an M12 spline. Hold the wheel with your left hand and apply slight force with your right hand, and it will come off.

How to Deal with the Non-Rotation of the Skoda Superb Fan?

The fan not rotating may be due to insufficient water temperature. You can turn on the air conditioning to check. If it still doesn't rotate, check the fuse. Check the fuse located next to the battery, the third fuse (locking a row of wires), or check the 10A fuse plugged in above. Check if the fan wiring plug is loose or if the circuit is disconnected, and whether the temperature control switch is functioning properly.

Where is the headlight washer switch on the Skoda Superb?

The headlight washer system refers to a water outlet located below the headlights that can clean dust and dirt from the headlights. Generally, higher-end models are equipped with this feature. During nighttime or low-light driving conditions, rain and dust can reduce the illumination of the headlights by up to 90%, severely affecting the driver's visibility. It is located on the panel below the headlight switch on the left side of the steering wheel.
