Clio Dynamique boot latch

Hi all, just bought a Clio II Dynamique, it's all good except from a few of Renaults well known problems.

One of these being that when I went to lock the car the doors locked like they should, but the boot wouldn't lock.

I got the rear door apart the other day and I managed to get it to lock just so that my car didn't get broken into.

When I press the button to open the car I can hear the motor whirring away in the back and the doors open. It's a shame that the friggin boot doesn't.

Wondered if anyone else has had this problem and if there is a simple fix to it

Thanks
