How to diagnose and solve the problem of LED headlights on a Mercedes C-Class

Model: Mercedes Classe C W205 - Years 2014-2021
Part: Headlight

In this video, we can see how to solve the problem of LED headlights fogging up from the inside on Mercedes C-Class cars: the first thing to do is to check that the headlight does not have any external damage and then, opening the hood, we verify that the seal is also good from the inside, where the connector must be in perfect condition. If everything is sealed, we start defrosting by starting the engine after connecting the battery charger. We should turn on the high beam for about an hour, or until the headlight is defrosted. These are common information for all cars that can be done as a DIY project: from here on, we must rely on a Mercedes workshop, which can understand how to fix any malfunction through the Xentry tips diagnostic system, owned by Mercedes workshops.
