Decoding VW Specific OBD2 Codes

While generic OBD2 codes apply across all car makes and models, Volkswagen also has manufacturer-specific codes that provide more detailed information related to their vehicles. These codes, often starting with a “P” followed by “1XXX,” pinpoint VW-specific issues, offering a more precise diagnosis. For example, a generic code might indicate a problem with the emissions system, while a VW-specific code could identify the exact component within the system that’s malfunctioning.
