Ford fiesta 1.5 tdci 6mx65 clutch replacement air.

Hello Guys,

Ford fiesta 1.5 tdci (2017 new model) 6mx65 gerarbox

I have a problem with my own car.
The clutch and hydraulic slave cylinder is replaced.

After replacement we put several syringe with brake oil in the line, but on the top in the reservoir came bubbles.
This clutch slave have no bleeding nipple, so we make the hose loose and air comes out, we did the pedal method many hours but i think it take false air.

There is no leakiness what we can see.

So what is next?

Does someone have ideas?

Thanks for your help guys.
