My dad's 04 2.0 dti had the clutch and flywheel replaced a few months back and since then he has had to bleed the clutch around five times as it keeps going to the floor. I told him to check the master cylinder and re bleed the clutch which fixes the issue but only for a few weeks. He checked and the mechanic that did the work said he replaced the slave cylinder. Just wanted to ask is there anything I should check for or anyone had a similar issue?
