Reset check engine light on mercedes?

To reset the check engine light on a Mercedes, you can use an OBD-II scanner to clear the trouble codes. Simply connect the scanner to the vehicle's diagnostic port, read the codes, and select the option to clear them. Alternatively, you can disconnect the car battery for about 15 minutes, which may also reset the light. However, ensure that the underlying issue is fixed before resetting the light to avoid potential damage.
