hi lee im a renault tech the best and cheapest thing to do is to go and buy a tailgate switch from your local renault garage and replace it youself... its nice and simple to do all you need is a flate blade screwdriver to pop the switch out them just clip the new one in. this fault is most common with the megane cc but can also occure on other models... let me know how it goes...
