Power Steering Whine

Hi All,

My car has develped a loud whine from cold. There is fluid in the reservoir, does anyone know how I can drain the system so that I can put some new fluid in? Is there anything else to check why it might be making this whine?

On another note, i had issues with the car running badly and not engaging VVTI, i cleaned out the MAF and the car is like new nowm pulls strong and hard.

Thanks in advance
