Hello team,
I bled my system a while back and put in new green hydrolic fluid. The whining went away for a bit but came back promptly. I think air was coming in from one of the hoses

After driving I found i bit of Pwr. Steering fluid on the top of the reservoir. But it looked like the return hose was leaking. Having already put the new fluid in, I just wanted to replace the hose, i disconnected my lower power Steering return hose. Drained the fluid from the reservoir that way and then, reattached the lower hose. At this point i forgot to prime the hose by unattaching it where it connected to the reservoir and turning the wheel back and forth until power steering was coming out.

Instead, once I drained the reservoir, I simply installed the new hose and and filled the reservoir back up. With the cap off (and the car off as well )I cut the wheels back and forth but didn't seem to hear the same amount of gurgling I did the first time (when I put new fluid in). The new hose isn't leaking but all the wheel turning in the world (car off and then on, with periods of time in between to allow the air to collect) didn't seem to bleed the system properly and it whines all the time.

Any suggestions?
P.s. should the Pwr. Steering fluid sit level in the reservoir when the car is on, the cap is off, and the wheels are not being turned?

Couldn't I just have introduced air Into the system that can't escape.

How does one confirm power steering pump failure

its a self bleeding system. yes, they can suck air in, between the pump and the resevoir, but the rest is high pressure fluid.. the only other problem you might have is a blocked filter inside the resevoir. are you getting a continuous frothing in the resevoir.

I mean, whenever I start the car and take the cap off, the fluid looks like there's a steady stream of fluid flowing up (churning up the reservoir). It's only once I turn off the car that the fluid turns frothy.

The pump is constantly flowing fluid in a circular loop back to the reservoir. When you operate the steering the fluid is diverted to the rack. As such there will be a ripple in the reservoir when the engine is running. Frothing is normally especially on new oil as it will contain air and other stuff even when new. As I recall you should take the level when the engine is off and the fluid cold. There are 2 marks and it should be at the lower when cold. Don't fill it to the top mark as this is the warm level.

I did not realize the marks were setup for cold and opperating temperature.

So I thought my hose was leaking and I replaced it with a fuel hose and I'm worried that may have been a bad plan.

I think your best to start again


Look at the Power Steering cap and tell us if it says MINERAL or HYDRAULIC fluid

Ummm..... mineral hydrolic I suppose. https://uploads.tapatalk-cdn.com/20170522/74105a0d9e9f4b70ba461ef3b98edb9b.jpg

okay, the most important thing is the number on the cap being G002000 . That's the spec of the oil needed.


So for me its follow this procedure. Vw Hydraulic Fluid G002000 - Vw Hydraulic Fluid G004000 (http://www.blauparts.com/vw/vw_fluid/vw_hydraulic_fluid.shtml)

At the bottom is instructions and keep the cap off whilst bleeding the system

I would drain the whole lot & start again

good luck
