2008 Mercedes-Benz E320 BLUETEC Problems

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.

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

2008 Mercedes-Benz E320 BLUETEC Reviews

I love this car. Great mileage and a 6 cylinder turbo diesel engine that feels like an 8 cylinder on steroids.

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.
