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.Google+

Check engine light came on and has been on for several months. Car failed CT emissions test due to engine light being on. Engine light is on due to camshaft problem and was told that this problem is endemic in this E350 and that there should be a recall by M-Benz. Mechanic says he needs to remove the engine to access and repair the camshaft issues and this will cost several thousand dollars!! Can anyone corroborate this problem in the E350.
I learned about a recall from a co-worker and decided to do an Internet search. After contacting the local dealer, I learned that there is a Mercedes Benz recall for the camshaft solenoid. They repaired the issue at no cost. If anyone was charged previously, you may want to demand a refund. February 2013.

Engg light came on while going to work, left the car and started the next morning. Engg light was off, car was driving fine. Took the car for service at Smythe European, San Jose dealership and mentioned the issue. The diagnostics came up with Camshaft Solenoid to be replaced. Checking on-line, I find that many E350 owners are facing the same issue..Mercedes should take care of this issue immediately.
Am getting my car back tomorrow, hoping i have no further issues..Am a happy Mercedes owner!

Purchased the car with 62400 or so miles and have never truly felt satisfied with the performance. I checked the drivers manual for the "comfort" setting as well as for the "standrd" setting. The manual suggests a differential is the shifting between the two settings, however there has been a noticeable issue with the timing/shifting of the vehicle since the time of purchase. This has resulted in a disappoining experience with Mercedes. I had a diganostic done yesterday identifying codes 1200 and 1208 which are associated with a "Worn Balance Shaft Gear", estimated cost is $4972.00.

check engine light came on. I took took the dealer and have found out this is a common problem with these car's. Mercedes- Benz as the leader should see this and take car of these problems for their owners when reported. As everyone know's nothing on these car's are cheap.
