You need to pull the radio from the dash and get the serial number of the radio which is on a label at the back.

Mercedes do not make stereos themselves but use various different manufacturers for their radios.

Once you have all the information from the label post it up and we can see if your radio is one that can be decoded by serial.

Coolant light wont shut off after adding cooland 1992 300te

Hello, If you are sure that the reservoir is filled properly, unplug the 2 pin connector on the side of the reservoir and see if the light goes out. If the light goes out, you need to replace the sensor which is what the connector hooks to.
