2004 Mercedes-Benz C240 Problems

Brake Light Switch Failure May Cause ESP/BAS Warning Lights

The ESP and BAS warning lights may illuminate due to a failed brake light switch. Replacement of the failed switch should correct this concern.

The Differential May Develop Leaks From the Seals or Cover

Leaks may develop from the differential cover and/or seals on high mileage or older vehicles. Our technicians recommend a complete reseal of the differential unit if these leaks are addressed.

Dead Battery Due to Failed Seat Control Module
