2009 Mercedes-Benz E320 BLUETEC Problems

Drive Train -- Verified

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.

Electrical & Lights -- Verified

The early versions of the central gateway module (which allows different systems to communicate with each other) have software problems. 

Electrical & Lights -- Verified

Lack of audio or cell phone functionality may be related to the failure of the audio gateway module.

Drive Train -- Verified

The electrical connector at the automatic transmission may leak fluid into the wiring harness. If not repaired, the oil will migrate through the wiring harness and damage the transmission control module. A new harness and control module may be necessary to correct this problem.

Electrical & Lights -- Verified

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.
