The pump motor is attached to the fluid reservoir, which on the W211 is buried down inside the right front fender; to access it, I need to jack up the car, remove the wheel, remove a half-dozen or so assorted fasteners, then remove the fender liner. You may be a more efficient mechanic than I, but this would take me far longer than 10 seconds.

On the other hand, checking a fuse would take me about 10 seconds.
