How to Replace the Front Reversible Tensioner | Mercedes-Benz W205 Models Front Seat Belt Buckle

Mercedes-Benz vehicles are equipped with seat belt tensioners that can cinch the seat belt during a crash event. Once the tensioner is activated, it has to be replaced. Your customer may also visit your shop due to a driver display message stating Front Right Malfunction, with an airbag symbol. Once the new part is installed, it will need to be properly commissioned and SCN coded. See our video on How to Commission the Front Reversible Tensioner | Mercedes-Benz W205 Models Front Seat Belt Buckle for the commissioning procedure.
