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.

 

Did you buy the car brand new ? If not was it ever involved in an accident ?

 

Hi, not new but never involved in accident. Was CPO'ed and still under Power15 warranty. Have done annual services only at official dealer during its life and twice after I purchased. The sound developed a year after I bought it and seemed to be not there during summer. Only reappeared recently.

 

The noise seems to go away after driving 20-30min

 

Sounds like it could be an issue with the PAS motor. Have you taken it to a dealer yet?
