This is similar to the 'clutch catches very high' question but obviously the opposite.
It's a Peugeot 206 X reg and I have had it since 30K miles and it has run fine and I and the previous owner looked/looking after it. Basically I need my foot firm to the floor now (65K miles on the clock) otherwise I get that dreaded crunch noise you get when you don't put the clutch pedal down enough. It has always need a bit of travel when you press on the clutch pedal but I believe it used to be a bit better than this.
The clutch does not slip at all and the car runs great. Is this indicative of anything going wrong, does it just need the clutch cable replacing?
