The clutch pedal suddenly without warning has next to no pressure and only dis languages at the very bottom of travel. The clutch was replaced only 12k ago so thinking it might be something to do with air or low clutch fluid...anyone know how I can bleed or top up this closed clutch system...

Hi I have exactly the same problem, I have been through some easy checks oil and filter change, air filter and hoses. It is a freelander 2 with 76k on it. I did have remap 5k ago but it has only just started snoking and much worse ehen towing. Any thoughts very welcome
