2009 Mercedes-Benz E350 ProblemsCheck Engine Light Due to Faulty Camshaft Adjuster Solenoid
The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.
Irregular and premature tire wear can be caused by the front thrust link bushings cracking and causing excessive movement in the suspension. The thrust link bushings are fluid-filled (to help reduce vibration), so if they crack, they will leak oil.
The ESP and BAS warning lights may illuminate due to a failed brake light switch. Replacement of the failed switch should correct this concern.

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?
