Mercedes-Benz E320 CDI Problems
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.
Lack of audio or cell phone functionality may be related to the failure of the audio gateway module.
The release tab for the center console can fall off unexpectedly.
Irregular and premature tire wear can be caused by the front thrust link bushings cracking and causing excessive movement in the suspension. The thrust link bushings are fluid-filled (to help reduce vibration), so if they crack, they will leak oil.
