Common Mercedes OBD2 Port Locations
Although the specific location differs across models, there are a few common areas where you are most likely to find the Mercedes OBD2 port:
-
Under the Dashboard (Driver’s Side): This is the most frequent location. Look beneath the steering wheel column, often near the pedals. You might need to crouch down to get a good view. The port may be exposed or hidden behind a small plastic cover.
-
In the Glove Compartment: Some Mercedes models conceal the OBD2 port inside the glove compartment. Check the upper section or the back wall of the glove box.
-
Center Console: Less commonly, the OBD2 port might be located in the center console, either in the front section near the gear shift or under the armrest.
-
Near the Fuse Box: In some cases, the OBD2 port is positioned close to the vehicle’s fuse box, which is often found on the driver’s side or passenger side footwell, behind a panel.
It’s important to note that even within the same model line, the Mercedes OBD2 port location can change between model years or trim levels. Always consult your vehicle’s owner’s manual if you are having trouble locating the port.
