F1 pump reservoir empty

It can’t be completely empty if the pump is running, then shutting off. If it was completely empty the pump would run continuously.
It sounds like the fluid level is just below the baffle that you can see in the picture. I would check for leaks under the car and top off the fluid. You’ll only need to add a little. The fluid level should be to the top of your fingernail above that baffle.
I’m sure you didn’t do any damage to anything, but may have a leak. Or the last person to check it didn’t check it correctly.

FYI, on my 355 it can take longer than overnight for the fluid to go back into the resovoir. Not sure why, but it does happen. I would put a small amount of fluid in )5mm) above the baffle/plate you can see and check it again in a few days.

 

Overnight the fluid level should revert to near the top as the pressure falls away. With the drivers door open it should pressure up and be 18 mm above the plate. Are you sure the pump is not cutting in overnight due to a faulty door switch or other reason. There is a fuse behind the seats, if you remove this it will stop the pump from running, fill the tank with 18 mm over the plate and see if it rises to the top overnight.
If you look at the tank the plate is at about 1/2 height so you should still have about 180 ccs to plate level.
The owners manual lists 2 different fluids for the power steering and the F1 system, you can use the F1 oil in both as a higher spec than power steering

 

if you want to depressurize the system, open hatch, turn key off , close door wait a few then turn nut type screw on power unit and immediately close after pressure is released

 

I use Mobil 1 ATF in mine. I bought the car 2 years ago and the service records didn’t indicate what was previously used.
The color and consistency matches the ATF and it’s been working good for me. I used my Launch to do a bleed/flush of the system.

Check the color of what's in there ..if red Mobil 1 sync att is fine..if green or amber ask dealer to top off or pick up some at dealer who did the work ..you don't want to mix ATF with other hydraulic fluids like CHF

Did you figure out what was happening? I’m curious. Did you have a leak?

Your last statement and the fact the fluid is low all point to a failed accumulator especially if no leaks and you don't ring level to proper level

1 second is too short .. when the diaphragm fails the fluid fills the gap this a lower level

Again this is assuming the level was good at some point and no external leaks

Do you have 18 mms above the plate with system pressurised ?

 

Correcting some typos ..sorry

.. especially if you have no leaks and fluid is/ was at a proper level at one point

When the diaphragm fails in an accumulator.. the fluid fills the gap and causes a lower level in reservoir

A quick check to see if accumulator is bad is to turn key to on position and wait a few minutes ..note duration of pump cycles .. also after that test with key still on shift into first and neutral and reverse noting how many shifts before pump cycles and duration of pump "on"

Report that back here and we can fairly diagnosis if the accumulator is the issue

Ok .. definitely is pointing to the accumulator if the level was good at some point and no external leaks which based on your comments that is the case

I would release the pressure as i mentioned in a prior post and see what color it is .. if red add Mobil one ATF and see if problem still exists ..if it does it is 99.99% accumulator
