as said above pipe off drain fluid, if I were you I buy 5ltr of fluid change then leave it a week or so and change it again flush all the crap out of it, re the cause of the contamination, PS problems are usually leaks or worn pumps, the only time I've seen gunk like that is when someone as topped up the PS res with coolant or washer fluid, last year my father in-law asked me to change the brake pads on his C8, I didn't bother asking him why just assumed he'd checked them when I removed the wheels the pads were like new so I asked him why he'd thought they were worn, he said well the brake fluid level was very low which can indicate either a leak or worn pads, I had to agree with this logic so if the pads were OK then the fluid had gone somewhere so I looked for a leak and found nothing it was then I asked him where he'd put the brake fluid and (you guessed it ) he indicated the PS reservoir, 1/2 litre of DOT 4 in the PS system, nice
