What are the causes of Volkswagen hybrid system malfunctions?

[Luke]

Here are the specific causes of Volkswagen hybrid system malfunctions: Ignition system or fuel system issues: The malfunction manifests as the car failing to start, mostly due to problems with the ignition system or fuel system, which can be diagnosed based on the cause of the stall. If the car stalls during driving due to non-human factors, such as bumpy road conditions causing the car to stall while shaking, it indicates an ignition system fault. If the stall is due to insufficient power, it is a fuel system fault. Battery issues: The malfunction manifests as the starter being unable to rotate or having insufficient speed. Check if the battery terminals are loose or oxidized, tighten the terminals or clean them; check the battery charge, turn on the headlights or interior lights, if the lights are dim, insufficiently bright, or turn off when starting, it indicates the battery is low on charge, charge or replace the battery.
