2009 Mercedes-Benz E350 ProblemsRough Shifting of Automatic Transmission
Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition, most commonly going up from first to second gear and going down from third to second or second to first gear. Our technicians tell us this is due to an internal component failure. Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.
The ESP and BAS warning lights may illuminate due to a failed brake light switch. Replacement of the failed switch should correct this concern.
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.

I had a 2000E320 with an "EC" setting which allowed me to bring in outside air when the weather was pleasant without engaging the compressor. Does my 2009E350 have that? Can I turn on the heat without the compressor being engaged?
