I'm not sure that will give me an accurate diagnosis. I may lose pressure once a month or at times a few days in a row. Sometimes one or two manual pumps and I'm away, other times I may have to pump for 3 to 5 mins before O gain pressure and it may or may not go quickly again

Bigjohn, Appreciate the reply. Sorry i keep mixing them up, yes it's the master i have replaced and the fluid level in reservoir is not dropping which is confusing me

Hi all, 2014 2ltr tdi Estate. Clutch pedal losing pressure regularly and I have to manually pump pedal to gain pressure. I have replaced the slave but no joy. Now looking at doing the master and while going that far may aswell do clutch plate so before incurring this cost are there any other possible causes? Is there a non return valve somewhere in the system getting stuck or will I just go ahead with the full job? Any thoughts are welcome Thanks Niall
