The Mercedes-Benz C-Class is a popular choice among car buyers who are looking for luxury but prefer a smaller vehicle. The W203 line has been the German automakers answer to this and they have been producing these smaller sized executive vehicles since the early 1990s. Even as customers remain loyal to the brand, they do experience problems, like the following:
Sunroof Malfunction: Class C owners have noted an issue with the car's sunroof failing to close properly. The problem could very well be a simple matter or dirt in the track. It may be an issue that is related to cold weather or it might possibly be an electrical issue in the motor of the sunroof. Whatever the cause, it should be looked into.
Cam Magnet/Sensor Leaking: Some Mercedes-Benz owners have reported that the cam magnet sensor leaks oil into the wiring harness. This may be a small leak now, but it will definitely worsen over time. This part needs to be replaced to prevent more serious engine damage caused by the oil.
Air Conditioning Problems: A leaking, nonfunctioning AC unit can be very frustrating, especially in hot weather. This is a matter of comfort, of course, but it still should be addressed.
SRS Warning Light On: If your SRS warning light is on, this can be an indication of a problem with your car's safety features. This is something that you cannot afford to ignore.
Suspension Noises: Unexplainable suspension noises are certainly very common across a wide range of motorized vehicles and Mercedes-Benz models are certainly no exception to this. Sometimes spraying lubricant on the suspension parts may eliminate the noise, other times more major repair may be required.
If you are experiencing one or more of these problems, regardless how major or minor they are, it would be wise to take your Class C into an independent Mercedes-Benz repair garage for an evaluation.
