Hi Guys
Many thanks for the comments so far.
I have to say, until i read Andruec's comments re the 'notch' at the end of the pedal travel, I had no idea such a notch existed.
Yes I can feel the notch now, but I never get to that position in normal driving.
I'm fairly sure that the reluctance condition did not exist when the car was new, i only noticed it earlier this year, after a 6 week layoff in hospital.
I think i will have a word with my dealer, since it's not just me, and see what he says.
