Following some sound advice and information gleaned from this forum I took the car back to the Car Shop in Northampton complaining about the pedal vibrations etc..

I've just given them a call to see how they're getting on with it and the guy said "it's in the garage having a new clutch & flywheel put in"

Result!
To be fair they've been great about it, I never took out the extended warranty and it was all done under their 3 month Engine & Drivetrain warranty.

Now, where did I put the contact details for 'Bluefin'?!
