2015 S550 power steering whine/is ABC fluid low?
I have a whine when turning the steering wheel. Don't see a "power steering reservoir". Does the power steering use the ABC fluid? I do see that reservoir. Is the system combined? Should I check the ABC fluid? Are the 2 even related? under 39k on the clock. Any help will be appreciated. Thank you

Yes power steering is ran off of the ABC pump. My pump had to be replaced and it started with the same issue you have. A while that got worse with time.
