Engine noise-Whining--2011 C300
I've got a weird noise I'm trying to isolate. The noise sounds like what you would expect from a failing power-steering pump, its a mid to high pitched whine like a failing bearing. It sounds like the whine is coming from the passenger side in the area of the oil filler/timing chain gear. The sound increase with engine RPM. It may also be coincidental but the check engine light came on around the same time as the sound started. It also feels like whatever is causing the noise is bogging down the engine a bit like I'm pulling something or have the car loaded. Scratching my head at the moment. Has anyone else had a similar issue?

Yeah, mine whines slightly too, nothing weird - it's been like that forever.
Would be helpful for the OP is he/she takes a video.
