OBDII Location Mercedes Benz: Finding Your Diagnostic Port

Every modern vehicle, including Mercedes-Benz models, is equipped with an OBDII port. This port is your gateway to accessing your car’s onboard computer for diagnostics and maintenance. Connecting a diagnostic scanner to this port allows you to read trouble codes, monitor vehicle performance, and ensure your Mercedes is running smoothly. However, the location of this port isn’t always immediately obvious. This guide, compiled with information from our community of auto enthusiasts and experts, will help you quickly locate the OBDII port in your Mercedes-Benz, saving you valuable time and getting you started with your vehicle diagnostics.

Since the introduction of the OBDII standard, all vehicles feature a standardized 16-pin connector. As mandated by the OBD standard, this port must be located within the passenger compartment of the vehicle. While standardized, its exact placement can vary depending on the specific Mercedes-Benz model and year. Locating it can sometimes feel like a mini-puzzle!
