Is a peugeot still under warranty 3 years on? Would expect the cable to be replaced unless they class it as a serviceable item... Don't think it would be a serviceable part though so should be covered
If its still under warranty and its a cylinder thats gone then i'd say yes.......the actual clutch/pressure plate i wouldn't think so. Unless its very low mileage and they show a bit of good will........ask nicely and see what happens.
