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.

Mercedes-Benz E320 BLUETEC Problems
The early versions of the central gateway module (which allows different systems to communicate with each other) have software problems.
Lack of audio or cell phone functionality may be related to the failure of the audio gateway module.
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 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.

Mercedes-Benz E320 BLUETEC Reviews
I LOVE this car! fuel mileage is great, power is wonderful, takes corners terrific. I've put nearly 20k miles in six months and overall could not be happier. ONLY thing I'm not crazy about is the GPS, and the electronic "files" you have to scroll through to make changes... very cumbersome.
The cup holders are in the console to on e of the reviews. The only 2 problems. 1.heavy rain wipers do not keep up blinding. The AC cutting on and off at randomm took to shop with out any resolve at this time.
Can not believe it, my 2007 e320 bluetec without even one cup holder in front. MBZ driver not allow to carry drinks in the car? Stupid design.
Absolutely the best balance between economy and power.
I love this car. Great mileage and a 6 cylinder turbo diesel engine that feels like an 8 cylinder on steroids.
