SL55 clicking noise steering while parking

[bmac]

hi guys any ideas what this could be? seems fine while driving, just get a clicking noise while parking / very low speed turning.

Steering is powered by same pump as suspension...
Pump will fail either on ABC side or power steering
I had clicking noise on my cl500 but it was a suspension valve block
You'll need to get it on Star to diagnose
