    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. [​IMG][​IMG]

    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.

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

    On my Toyota rav4, it would start up but no power steering. Stop the engine and restart and it was normal. Ended up that I change the power steering fluid. May be worth changing it again before you start of the system.

    I think they have a relief valve in the pump so I think mine was stuck open when it did not give steering pressure. It might be a relief valve so flushing in the first point of trying to find out.

    Thanks. Steering feels almost completely normal. Not anything I could distinguish on my end.
