Mercedes-Benz C-class (W204) has many complex electronic systems, so problems with them occur quite frequently. Some of the most common of these are:
- Loss of "mass" of rear lamps. The end of time, the mass wire melts and the contact is weakened. This is demonstrated first by reducing the brightness of one of the headlamps and then by completely cutting them off. In order to avoid this, it is necessary to put the extra mass on the body.
- Defective steering module lock module, which can fully immobilize the car.
- Flats of electric motor of the fan
