Check engine light caused by Camshaft Adjuster Solenoid Failure
When I turned on the car the windshield wipers went on and wouldn't go off--even in the off position. I turned the car off and restarted it--then I had no windshield wipers and no turn signals. When I arrived home I turned the car off and removed the key--it kept "dinging" and telling me to turn off lights and remove key--they were both done. Meanwhile the check engine light was on. Since it was a Saturday and I knew the battery would be dead by Monday morning when the service department opened I had the car towed in to the dealership by Mercedes Roadside Service. The tow truck driver was able to "click" through the smart key and turn off the lights. Long story short, when the dealership looked at the car on Monday morning it was the solenoid something or was replaced for free as my car is still under warranty.
Replaced - under warranty
