Thanks all for your useful and interesting comments.
@Watts, I'm sure he hasn't examined the clutch. In fact I think all he has done is try the gears from cold, and pushed the clutch in a few times. It may be my imagination, but since he has raised this possibility, I do feel the clutch is slightly heavier than when I first bought the car ( the technician suggested I have not noticed the problem as I may have become used to it over time).
@KMP- thanks. Yes, so the fixed plan has identified a (possible) fault, which may be incidental, and essentially he stops there. The complication in this case is that under the terms of the warranty they won't pay for it, nor are they saying it will fix the problem I'm asking them to fix. I don't mind them replacing parts unnecessarily, so long as they pay for it. I have written to them insisting they investigate and rectify the gear selection problem..
@monkeyhanger. Thanks for the heads up- I appreciate I may have a battle. My argument is that it must be a manufacturing defect if it has failed at 8k. I can give details of 2 Peugeots, 2 Alfas, 1 fiat and 1 BMW all driven to high mileage on the original clutch. I'm actually pretty confident that when they investigate, they will find a defect- I cannot understand why the clutch would have worn.
Let's see how they respond. It's actually one of the reasons I don't buy warranties. You own the car, you break it you fix it. Far less hassle than this kind of battle!
