Due to the lack of documentation, there is no confirmation that the screw connections of the turbocharger’s oil-supply and oil-return pipes were correctly executed during the assembly process.
In the event of a loose screw connection, oil might leak at the oil-supply and/or oil-return pipe of the turbocharger.
The leaking oil might then come into contact with hot components, increasing the risk of fire.
The Mercedes-Benz GLC models affected by this recall were equipped with a 4-cylinder petrol engine and manufactured between 5 March 2018 and 18 March 2020.
