Hey guys,

I have a 2000 Audi A4 b5 quattro 5spd 1.8t.

When I turn very sharp at low speeds (I don't turn that sharp while going fast lol) I hear this humming/whining coming from, what I assume is, my pump. It never used to do this and when I first noticed it I checked my power steering fluid and it was low so I topped it off (SO EXPENSIVE) assuming the noise would go away. The power steering fluid hasn't leaked or anything since. My friend suggested a bad seal or air in the system. The steering rack has been replaced in my car previously as well.

Is this normal/bad? Do i need to replace the steering pump?

 

Check for seepage around the suction hose from the fluid reservoir and at the suction hose to pump connection.

Over time, the hose can become dry and the Oetiker clamp will not be able to maintain the seal so air is being drawn in around the hose connection at the pump.
