• Second Character: Indicates whether the code is generic (0) or manufacturer-specific (1).
• Third Character: Indicates the specific subsystem affected (e.g., fuel system, ignition system, transmission).
• Fourth and Fifth Characters: Provide more specific information about the nature of the problem.

Here are some common VW error codes and their potential causes:

• P0300: Random misfire detected. Possible causes include faulty spark plugs, ignition coils, or fuel injectors.
• P0301-P0306: Misfire detected in cylinder 1-6. Similar causes to P0300.
• P0171: System too lean (Bank 1). Possible causes include vacuum leaks, faulty oxygen sensor, or low fuel pressure.
• P0420: Catalyst system efficiency below threshold (Bank 1). Possible causes include a faulty catalytic converter or oxygen sensor.
