If you not sure there’s an active recall for your car, you should make contact with a Mercedes-Benz dealer or workshop that’s been officially authorised to perform repairs on behalf of the manufacturer.
Locate a Mercedes-Benz dealer to check the recalls history
You will need the VIN code of your vehicle, which is a unique identification number that is embossed on the body of the car and shown on the ID card. Most models sold in the EU have it shown near the bottom of the windscreen. It is made up of a unique combination of 17 letters and numbers.
Write a simple request to verify the VIN code of your vehicle. Ask the dealer, if any Recall or Technical Service Bulletin has been issued for your car in the past. You can use the example request from this page.
