What Causes the Audi A3 to Report a Vehicle Electronic System Malfunction?

[StElliott]

Audi A3 displays a vehicle electronic system malfunction on the dashboard after startup, which is caused by insufficient battery power leading to momentary voltage drop during the startup process. Solutions for the electronic system malfunction are as follows: 1. Reset the electronic system: Press the electronic parking brake downward for 5 seconds, then pull it upward for another 5 seconds to initialize and reset the electronic parking brake. 2. Parking brake: Typically refers to the manual brake installed in motor vehicles, commonly known as the handbrake. The handbrake is usually located within easy reach of the driver's right hand for convenience. 3. Function of the parking brake: It stabilizes the vehicle after parking to prevent accidents caused by rolling on inclined surfaces. 4. Electronic parking brake system: Some automatic transmission models on the market feature a foot brake near the driver's left foot, which serves the same function as the handbrake. Advanced models may also include an electronic parking brake system.
