also worth checking that the level of oil in the hydraulic fluid reservoir if its low then you'll need to top it up and then bleed it
however this isn't something that can be done without the diagnostic kit ( SD3)
F1 Gearbox procedure (not for manual gear) :
1- Connect the SD-3 system to the diagnosis plug-in.
2- Choose "Diagnosis" from the main menu.
3- Choose "CLUTCH DRAINING" from the "DIAGNOSIS" menu.
4- Add oil into the tank to prevent the oil level from running low.
5- Press "ENTER" to activate the tester.
6- Open the clutch draining union and wait 3÷4 seconds to let the oil flow out.
7- Close the draining union once again.
8- Top up the oil level in the tank.
9- Repeat procedures 6-7-8 two or three times, on both draining unions.
10- Once this operation is complete, lock the unions to a torque of 18 Nm (Class A).
11- Wait for the tester to exit the draining procedure and to display the related positive result.
12- Shift gears a couple of times and top-up the level.
In the system, as well as the union (Pic 1) on the gearbox, there is also a second union (Pic 2) on the block for the clutch pipe rapid coupling, located in position with the right-hand rear fastening point of the gearbox support frame.
