360 Strange “beep/whine” from F1 power unit

My 360 has developed a strange noise from the F1 pump area. I have kind of narrowed it down to the top right hand solenoid on the pump itself. When I first heard it I thought it was the accumulator ball so I replaced it and I must say the car shifts better and quicker but the noise is still present. The noise appears after the pump cycles and pressure builds in the accumulator ball. I have a video but I need to figure out how to post it

The solenoid I am referring to is marked EVF on the actuator body itself.

Can anyone tell me what part number solenoid valve is used in the port marked

• EVF (QPV) – clutch engagement

I have seen 195717 and 195719 solenoids used, Because this car was not purchased new by me I just want to verify that the correct one is in there now. Or if there is even a difference in those two part numbers

 

Ok, I have found out some more information.

The valve block / power unit of the Ferrari F1 system contains 6 solenoid valves.

• EVF (QPV) – clutch engagement
• EV1 (PPV) – gear engagement
• EV2 (PPV) – gear engagement
• EV3 (QPV) – gear selection
• EV4 (QPV) – gear selection
• EV5 (QPV) – gear selection

part #'s for QPV 195717
Part #'s for PPV 195719

I have ordered a new QPV solenoid and will post back with results once I receive/install it

 

Qpv valve just came in today from Sequparts in Germany, I will get it installed in the next few days and report back.

OK, I got the solenoid installed yesterday and the noise seemed to go away........Momentarily now i hear a longer beep that seems to be coming from the pump itself ( I did replace the electric motor a few years ago). It might just be air and need to be purged correctly using an SD2. anyway it was too hot yesterday to look any further, I will update again once I figure something out.
