Persistent Power Steering Noise

[Thom89]

Sounds like cavitation, possibly your steering rack or pipes is leaking air into the system, or a simple air lock somewhere.
Unlikely, but seen it happen before, just double check that a clamp has not accidentally been left on a flexible pipe somewhere!

I can't seem to find any leaks anywhere and I've done the usual bleeding practice. The belt has a good tension with about 5-10 mm of moment when you press on it. Think i'm gonna send back the after market pump and fit a refurbed genuine.

Take the PAS belt off and run the engine tell me the noise is gone or still there?

[Adamkay]

Have already tried this and there's no noise with the belt off.

Fitted a reconditioned genuine pump and all is good now. Never buy a Meyle pump. No longer German quality but cheap Chinese rubbish.
