Good idea if it hasn't been done in many years or 10's thousands of miles. I did mine a while back used a large syringe, sucked out as much as I could from the reservoir, topped up with fresh fluid, moved the steering from lock to lock a few times and repeated until the fluid was the same colour as new.
Did notice any difference but was easy enough and another job done.

Whats your mileage.
Get it done if your around 75k miles.

Easy enough to do yourself if you are handy and have the space.

Summary; Use a turkey baster to empty tank. remove and seal return. fill tank. suck from return pipe till it runs clear (turning lock to lock). put return back on and check level.

Hi all! I got the steering flush done at the service center,flushed through and cleaned with new fluid and conditioner added,the old fluid was discoloured,yellowish,probably a long time in there it seemed.Thought it better have it changed because the C220 engine weight is fairly heavy on the front wheels as C220 owners understand.Thanks for all the interest,appreciated.

yes

the commons stuff is not the same as each manu spec. the one you list makes the steering heavy on Ford Focus Mk2, swap back to the ford stuff and its much lighter

and that's another round of confusion, Red PAS (aka std auto box fluid) is susceptible to over heating and falling to bits and often needed an oil cooler.... as the world moved, in 2005 the law said manu have to be responsible at end of life. So many manu ditched red and went with various hydraulic fluids that are more temp stable can have smaller reservoirs and no oil cooler (cheap / less enviro mess at end of life)

depending upon which factory built it, all Focus Mk2 were supposed to have green PAS fluid, but some factories used up old stock and filled many with Red..... Same on Alfa except on Alfa seems the seals fail - fords don't care
