On a merc this is either the cam position sensor or or the cam position magnets. MB has an updated magnet design. Its not that serious a problem and about the only thing you may notice after fixing it is a smoother engine. This should be still covered under warrenty.
States B camshaft over ********, Bank 1. I can tell you some general things about this condition.

Each manufacturer has its' method of optimizing timing performance. The camshafts no longer are fixed in a single position in relationship to the crankshaft.

Just as some makers used to use chains or gears to time the camshafts, the makers advanced to mechanical or electrical-mechanical attachments to adjust the cams' position.

In some designs, an electric signal adjusts the position. In other designs it is strictly mechanical and automatic.

I am unfamiliar with your specific motor. On a Mercedes the part you need to replace may be externally serviceable with a plug-in part or may require removing the camshaft through the top portion of the engine.

The part you need may be called a Camshaft Actuator, Camshaft positioner or other term.

I hope my solution is helpful, and a parts search may give you a better idea of the shape and location of this part. Please rate my solution.
