How do you drain all the power steering fluid out of a 96 audi a4 2.8 front wheel drive?

Someone added lucus to the power steering fluid and it makes noises now. So I want to drain it all out and put Audi power steering fluid in.|||undo the return pipe under the reservoir and lead it down below the car most of the fluid should run out the return pipe is the bigger rubber one usually perished so be gentle. put a container under the reservoir first. easier way is to use a turkey baster or similar to suck the fluid out of the reservoir and refill it and repeat this a couple of times after a short run
