Mercedes-Benz E350 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your Mercedes-Benz E350

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 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.

The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

I have a 2006 E350 and need a Schedule C Maintenance Check-up. After consulting the owner's manual, it is difficult to determine exactly which items need to be checked. Can anyone provide a list of Schedule C items to be checked?

Purchased 2006 E350 with 55K miles in 2009. Loved the ride and the handling. Great car for my sales job. At 110K miles in 2011, car began to shimmy on a cold start. In later weeks, the car would shake violently on start up. Was told that it was a "balance shaft rotor", a small part about the size of a lipstick case deep inside the engine. Apparently for 2006 and other similar years this part wa...

After returning to the car (apx 20 minutes), I start the engine and it immediately turns off. A second try is necessary to get going. The dealership has no idea why this happens and their service manager and service technician ha...
