Help! Steering buzzing/humming while at idle

Model: 2016 488 GTB. Hey guys,

Thanks in advance. Noticed the issue about 6 months ago. steering wheel makes humming/buzzing noise at idle after cold start from sitting, amplified when turning the steering wheel left or right. Also, slight clunking noise when doing parking maneuver after cold start which goes away once car is hot. The humming noise increases pitch when driving from full stop up until around 10-15 mph and it disappears. Just did the annual service in August. Power fluid is normal as attached. Wondering if this is normal or not. Here's the brief vid of what's happening.

 

Bumping this.
