Guys.

Im about to be driven mad by a knocking noise from the rear of my new car.

I have removed everything from the boot and i still get the knocking noise when going over rough road/potholes

I have pulled the back seats down and it stays the same.

One thing i have noticed is that i have to seriously bang the hatch down to get it to lock, if i just let it fall under its own weight or a little thud it will not lock shut.

Anyone got any experiance of this? How willing are VX to fix squeeks/rattles and bangs?

Cheers
