I have 2004 vow Passat v6 that started making a power steering noise bought a rebuil pump and put it on blead the system until there was no air bubbles started it up and still made the noise .

SOURCE: power steering fluid blowing all over engine compartment

somewhere there is a air leak on the suction side of the pump.  Try tightening the clamps and connections.

SOURCE: steering wheel noise

have someone turn the steering wheel will the car is running so you can look to see exactly where the noise is coming from. sounds like a dry steering component.

Oops, sorry about that.....

The power steering fluid reservoir is located just behind the drivers (LHD) headlight, just forward of the washer fluid reservoir.

The reservoir has a green cap on it and a plastic trim panel to conceal the sides, it is circled here:

hallo
if power steering fluid is bubbly, means that its sucking air somewhere before(sucking side) (or on) power steering pump. that would explain the noise. Check (when cold) fluid level. if level is low, top up before starting the car. had a lot of cars that high preasure hose was leacking fluid on restricting valve. if so, fluid comes out on the end of protecting cover of the hose. (driver side on spark plugs and down the engine). replace hose with original. do not try to make it your self, becouse steering wheel will shake, sinse restracting valve is missing.
But if you press brake pedal, that has nothing to do with it.

There is a tank under the hood with a STEERING WHEEL icon on it. DON"T OVERFILL and use only PENTOSIN
