What Is This ?
Anyone happen to know what this is? It's low of fluid but I'm not sure what type of fluid it needs. This is the M278 engine on a 2013 S550.
Power Steering Perhaps?

Thats the Power Steering Fluid Reservoir
Uses Pentosin CHF 11S Fluid.
Every 2 Years i suck out as much as i can and fill it with new fluid. Then start the engine and go lock to lock a few times and then check the level
Good luck.
