2003 Mercedes-Benz E320 4MATIC Problems

The Differential May Develop Leaks From the Seals or Cover

High mileage or older vehicles commonly develop leaks from the differential seals and/or cover. Our technicians recommend a complete reseal of the differential unit whenever these leaks are repaired.

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.

SRS Light Due to Damage from Liquid Spilled onto Passenger Seat

Water can damage the weight sensor in the front, passenger seat, causing the SRS (airbag) light to illuminate. There is an electrical component in the seat cushion susceptible to fluid damage. Any spills should be dried up immediately in order to try and prevent damage to the sensor.
