Introduction
A loud whine started being heard when the car was backed out of the garage. This happened most noticeably when starting the car while it had set overnight or at work all day. The sound would worsen when turning the steering wheel. The whine sound would go away after several minutes of driving.
It reached a point that that it was embarrassing, and left the steering a little on the rough side. A simple top off of the power steering fluid did away with the whine, and made the steering Mercedes Benz smooth again.

2. Remove the power steering reservoir cap by turning it counterclockwise as shown in Figure 2. When you pull the cap off the reservoir, be sure you have a rag ready to wipe off the dipstick on the underside of the lid. Fluid will drip off of the stick and cause a mess under the hood. Be absolutely sure NOT to get any contaminants in the reservoir. That includes lint from your rag.
3. Once you have removed the reservoir lid and wiped the dipstick clean, reinstall the cap back onto the reservoir. Remove the cap again and check the fluid level on the dipstick as shown in Figure 3. Is your car warmed up or cooled off? If your car is at running temperature, check the fluid level against the upper Max and Min marks on the dipstick near the 80°C (178°F) mark. If your engine is cool (at ambient temperature), then check the fluid level against the lower Max and Min marks on the dipstick near the 20°C (68°F) mark.
Is it low? Too much? If you are low then add a little at a time until you bring the mark on the dipstick up to or right under the Full mark for the appropriate engine temperature.

6. Crank the car up and listen to how quite she is. Ahhhhhh, reminds you why you purchased a Mercedes Benz. That's it, your done!
