Power steering buzzing

Have you def diagnosed it to power steering? Is the power steering a bit tighter to use?
Check the power steering oil level and if necessary top up and move steering full rack left then right a couple of times to re bleed. If that does make a difference, make sure and have a very good look to see where it’s leaking from.
Some time ago I had noticed a buzzing after a run and tracked it to the turbo Aux cooling pump that runs on for a few minutes after switching the engine off.
New pump and noise away.

Best to be sure first, using the parts cannon to diagnose things can make it expensive.

If it is the turbo pump that is buzzing, changing it is not too expensive nor that big a job with a bit of mechanical knowledge.
