Got the car back today, trying to change the the auxiliary belt to stop the squeak, possibly due to the fuel that was sprayed everywhere from the fuel filter when it was faulty.
I was out with the technician for about an hour regarding the clutch, he seems to think the clutch itself is fine, but does admit there's a problem, he's going to look at bulletins tomorrow, see if my car needs an ECU update and also get me a 110bhp 2.0TDI in to see if it's the same

Really helpful chap

So wish me look, my wiper was also banging on the side of the window, they've had to order a new wiper mechanism due to the spline not being adjustable? Strange?
