How to Read VW Golf Fault Codes

Retrieving fault codes requires an OBD-II scanner, a readily available tool. The process is straightforward:

1. Locate the OBD-II port, usually under the dashboard on the driver’s side.
2. Plug the scanner into the port.
3. Turn the ignition to the “on” position (without starting the engine).
4. The scanner will display any stored fault codes.

What do the codes mean?

Each code consists of a letter and four numbers. The letter indicates the system (e.g., P for powertrain, B for body), while the numbers correspond to specific components and malfunctions. Resources like online databases and repair manuals provide detailed descriptions of each code. You can find specific engine fault codes for the Mk4 Golf here: vw golf mk4 engine fault codes.
