A guide to problems, costs, maintenance and repair for your 2005 Mercedes-Benz E320 CDI

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.

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