P0011-Incorrect position of the intake camshaft
Mentioning that (might be helpful for others), I was having a terrible engine misfiring in my CL550 (C216), changed 2 or 4 ignition coils, set of spark plugs, o2 sensor, and lastly the issue turned to be in the ECU itself...
Then I changed my O2 sensors and haven't had a problem since.
Funny thing is, not one certified Mercedes mechanic could figure this out. Ended up buying a lot of parts I didn't need.
Good luck.
