Finding the diagnostic port on your Mercedes is crucial for troubleshooting and maintenance. Knowing its location allows you to connect diagnostic tools to retrieve valuable information about your vehicle’s systems, identify problems, and perform necessary repairs. This guide provides detailed instructions and helpful tips to locate the OBD-II port in various Mercedes models.
Locating the OBD-II Port in Your Mercedes
The OBD-II (On-Board Diagnostics, Second Generation) port is a standardized 16-pin connector found in most vehicles manufactured after 1996, including Mercedes-Benz models. This port allows access to the vehicle’s computer system for diagnostics and troubleshooting. While the general location is similar across most models, there can be some variations.
Common Diagnostic Port Locations in Mercedes Vehicles
Typically, the Mercedes diagnostic port is located under the dashboard, on the driver’s side. It might be tucked away behind a panel, requiring you to bend down and look upwards. In some models, it can be found beneath the steering wheel column, near the pedals. Less common locations include the glove compartment or the center console.

Model-Specific OBD-II Port Locations
Certain Mercedes models have unique placements for their diagnostic ports. For instance, in some older E-Class models, the port might be hidden behind a small panel beneath the ashtray. In newer models like the C-Class and S-Class, the port is usually easily accessible under the dashboard on the driver’s side. For detailed information on specific models, consulting the owner’s manual is always recommended.
