2009 Mercedes-Benz E350 ProblemsInternal Component Failure May Cause Rough Shifting
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.
Lack of audio or cell phone functionality may be related to the failure of the audio gateway module.
A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.

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?
