Three problems related to check engine light on have been reported for the 2010 Mercedes Benz E350. The most recently reported issues are listed below.

1 Check Engine Light On problem

Failure Date: 12/07/2017

The vehicle has only 50k miles. I am the only owner and I purchased the vehicle in 2010 (new) with only 9 miles. I have completed all required services to date. In may I had the ab service complete and the check engine light was on. I was told it was likely due to the need of having the spark plugs change based on time not mileage. Now I am being told the outcome of the check engine light on is due to a misfire code for cylinder one, failed sds compression test. Cylinder one failed cylinder leak down test at 80%. Exhaust valve seats failing causing exhaust valves not to fully close. We are unable to repair the valve seat on cylinder head and it is necessary to replace passenger side cylinder head. Only camshafts and cam adjusters can be transferred. New head will come with new valves. There are repeated reports from other owners with this same issue-resulting in enormous repair cost. This is a defect and mercedes-benz need to consume the cost, especially since the vehicle has less than $50k miles.
