Its cable
Get the front end up in the air on stands or a ramp- not a jack…..
Look up at the gear box pretty much directly behind the where the front fog light would be on the drivers side if its euro set up.
You will see an arm sticking out with the cable going in.- release the cable from it and see if its sticky by hand, the leverage and force put into the pedl meant i never really noticed it being sticky with the pedal.
Mines had rubbed through on an attachment to the bulkhead and was jamming the inner , worked 90 times out of 100 or there abouts,
Easy swap, highly recomend getting an oem from the dealer over getting a pattern part, although the real deals a bit tougher to fit/get through the bulkhead.
You can move the arm in the box back and forth but it needs a hella force to do so, i stuck molgrips on mine when testing it.
Release bearings go on these as well ‘ making a howling racket when you sit at idle – goes away if you rest your foot into the slack at the top of the clutch,
