My megane 1.5 dci (2006) boot keeps opening when I go into reverse(sometimes) or put on rearwindow wiper. it is intermittent.

It sounds like a short circuit between wires. If reverse lights are on the boot lid it is most likely to be on the wiring between the body and boot lid. Sometimes they break due to the constant bending of the wires. Also check any earth connections on boot lid and make sure they are clean and tight.
