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 ESP and BAS warning lights may illuminate due to a failed brake light switch. Replacement of the failed switch should correct this concern.
Mercedes-Benz E320 BLUETEC Questions
Upon entering freeway and stepping on gas, there was no power to gain speed. Took quite a long time to reach 60mph. Drove to Dealership. Initial diagnosis is turbo charge issue. What can I expect? A hose, maybe a gasket? What are labor costs involved for turbo charge related issues?
The gear shifts from N to D happens with a jerk and while driving the gear automatic gear shifting does not take place. The engine runs at high rpm. Then when I switch off and restart, the problem goes away.
This problem happens sometimes.
Restarting the engine seems to reset the sensor.

The Diesel engine may stall and not restart due to a faulty crankshaft sensor. Dealers will replace the sensor free of charge to correct the problem.
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 bought car used with 100,000 miles, Interior is cheap for a car that cost this amount of money new, Its not leather its' pleather(plastic) my little dog slides like she is on glass on it. The GPS stinks, Now the good part, 38.5 miles per gallon on the freeway, and about 26 city, very nice stereo, handles great, I have the fold down seats, great for long cargo, sun shade in the back keeps car...
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.
