Powersteering hose - bank check valve?
Planning on getting my PS (pressure side) hose re-done by a local hydraulic shop.
I've read that there'southward a cheque valve in the hose itself. Demand confirmation before I pull the hose out.

In that location are merely 2 things needed to brand an Audi piece of work properly - Duct tape and WD40. If it moves and it shouldn't - Duct record. If information technology doesn�t motion and it should - WD40.

Not certain. Just read it somewhere here or vortex.
Has anyone taken apart the hose?
Edit: are 8D1422893AL and 8D1422893K interchangeable? It's a huge jump in price $28 (febi) vs $314 (oem / not Audi branded)
Edit: checked etka Aeb uses a regular banjo (n90467404)

If pump to rack is what you lot are doing, a banjo similar to what I listed would let y'all apply a evidently hose.
It would need to go at the rack end.

Just checked etka over again. It does use a banjo bolt bank check valve. 
Same exact part number you posted 4d0422529h. Thanks

Check valve banjo on rack and regular banjo on pump. When my hose was leaking, I opted used OEM on ebay and never had a problem since. Placed amsoil ps fluid in also, with pentosin oem fluid flush.
The washers also say 14mm in the bentley manual. My 14mm crush washers did not fit, then only a heads up. Concluded up reusing the quondam ones. ID was not large plenty. Just by a tad.
I detest it when my motorcar acts similar a little bitch, treating me like a bitch

Heads up 
If yous for some reason take out the bolt and make up one's mind to make clean it with acetone: Don't .
I did and I think I deformed the little plastic piece that's in there. PS moans now...

But installed the hose. Oasis't test driven information technology yet, merely did a quick engine kickoff while on stands to bank check for leaks (nothing to little pressure?).
The banjo on the rack is accessible thru the bicycle well using a directly combination wrench (slight kink on the finish not beginning). Couldn't get to the banjo under the coolant tank or under the car with a ratchet+long extension. After removing the wheels and separating tie rod from the knuckle, information technology took roughly 10min to remove the hose. Under the coolant looks doable with an showtime wrench or thin ratchet+brusk socket but imagine it would be hard to re-install the banjo.
The PS hose (AEB) is just an inner nylon hose with holes every 2-3 inches, wrapped in loftier pressure level safe hose and so wrapped by another rubber hose. Outer hose looks like it's only for abrasion protection (non crimped at the ends). Hose didn't await special, looked like basic loftier pressure hydraulic hose.
Does the PS hose have a bracket? There'due south a 2inch metal collar in the middle of the hose. Non entirely sure what it's for.

Never use acetone on anything plastic.

Could also simply be air in the organisation. I bled my automobile so skilful before starting the car that I didn't take to add any after car started. Didn't drop from level after bleeding.

Yup loads of air. Took me a while to bleed it completely. Much more than when I did a fluid change a couple years dorsum

Does the hose have any restrictor in it? My rack now started leaking. . Possibly got damaged when bleeding? New hose is bone dry out, kicking is filled with oil.
I didn't call back seeing any restrictor on the hose when it was cut up. But thing that would've resembled a restrictor was the center neckband, but didn't actually seem to restrict anything since the inner nylon hose moved freely within information technology.
I as well reused the metal ends then any restrictor in it would still exist at that place.

Not that I know of. What process did yous employ for bleeding? What I did was utilise the starter to turn the pump for a couple seconds (injectors unplugged). At present this is the crucial part. With cardinal in accessory position, you chock the wheel fully left and correct a few times (I would do similar 5xs each side). Tiptop off reservoir and repeated with this process till reservoir level would no longer drib. Chocking the wheel left and correct with cap off reservoir is what clears air from the actual rack.

The high pressure line has a congenital-in restrictor. I've simply had a line fabricated today, and the section with the restrictor MUST exist retained.
I had a stainless braided high-pressure made for my Ur quattro many years agone, without a restrictor. The fluid bubbled similar crazy with the engine running, and of course the vane pump didn't like it. It was pumping more air than fluid, and was really noisy. Ability help was on and off.
I can take a motion picture of my high-pressure level hose tomorrow before I install it to my automobile, if that would assist.

Seerlah its already fully bled, but too did a lot of it on the basis since i didnt fully drain it in the air. Thinking vanes couldve gotten damaged.
Nolly yes please take a pic. When i had my hose made everything was retained from the former hose except the collar in the eye and hose itself. A new inner and outer middle collar was made. I didnt meet whatsoever restrictor pill inside or annihilation that resembled a flow restrictor.

Here are a couple of pictures of my ability steering high-pressure line. The crimp-similar fitting under the actual hose casing is a steel restrictor valve.

Thanks for the pics.
Guess i accept the proper hose/restrictor. That restrictor clamps the rubber hose to an inner metal pipage.
I did need to have that re-fabricated when the hose was fabricated. Was slightly tighter than the stock restrictor. By the looks of information technology it just restricts the rubber hose not the internal nylon hose. The internal nylon hose moved freely when it was still in the old hose.
