Ive got a 55 plate and its doing the exact same thing. Before I got the car I noticed the noise and I automatically thought it would be the release bearing. However the garage apparently took the box out and had a look and they said the release bearing was fine. One of the salesman told me it was a characteristic of the car. (bullsh#t)
Im in the same boat and confused
When I met up with Stew and let him here the noise, he never heard anything like it before.
Would be good if anyone could shed some light on this.
