How to Read VCDS Codes

Each VCDS code follows a specific format. The first letter typically indicates the system where the fault occurred (e.g., “P” for powertrain, “B” for body, “C” for chassis). The following numbers further specify the nature of the problem. For example, the code “P0203” indicates a malfunction in the fuel injector circuit for cylinder 3. Knowing the meaning of each part of the code helps you narrow down the possible causes and determine the appropriate course of action.
