I had a new clutch in my Citroen Xantia 1.TD about 5000 miles ago (mainly motorway). The plastic clutch clip broke yesterday and I was towed to the nearest Citroen specialist. They say the clutch has gone heavy and due to this a new clip would just break - so it needs another new clutch.
Is this reasonable? What would make a clutch go so heavy with such light usage? The clutch specialist who originally replaced the clutch is 20 miles away - unfortunately I've yet to be able to get in touch with them to ascertain their position, but I'd be grateful of any opinions of where to go from here and any alternative solutions.
