Three problems related to seats have been reported for the 2002 Mercedes Benz C Class. The most recently reported issues are listed below.
Defective seat controller modules ( driver and passenger ) cause the battery to drain completely within 24 hours. This leaves me stranded and unable to drive my vehicle. A search online reveals multiple other with the same issues. . . Indicating an obvious safety issue that is well known to the manufacturer with no resolution to this problem from the manufacturer other than paying $1000 for a known defective issue/part.
Seat controller modules, they constantly drain the battery when the car is off. This is a very very common problem with mercedes C Class. The controller drains the car battery to the point were the car cannot start, and continues to do this if the car is not driven everyday. Obviously having a car battery get sucked below 3v is not healthy for the battery, and in the end everyone with this problem has to replace their battery many many times.
Seat control module on passenger side drains the battery.
