Note: Due to the different model year and configuration, please provide the frame number (also known as the VIN number) before consulting/purchasing. You can check the frame number of your vehicle in the lower left corner of the front windshield or the 17 digits on the license plate. The Mercedes-Benz frame needs to provide the 17 digits. We will determine the accuracy of the parts for you according to the frame number you provide, so as not to delay your valuable maintenance time
