Bonnet wire

"To get to this cable there are two methods - raise the front of the vehicle, remove all the under side plastic trays and access the cable by reaching up into the engine bay - the second method which I used was to remove the nearside front black plastic grill by the headlamp - get your fingers under the bottom edge starting at the headlamp and pull upward, the plastic grill separates from the bumper and as you move along it's length it will release without damage. Get a good torch and shine it in - you will see a grey plastic grill up top of the radiator by the bonnet - pull that free, mine came away with minimal damage and I can't actually see what function it served anyway."

Don't know if this is any help mate?

 

I've found another thread that may help:

Not sure if it will though to be honest - has yours broken on the cabin side? Hard to tell from the pictures. If so, can you not grip the cable with some vice grips and pull?

 

There is a good chance its the same part yes. Can't see why Renault would make it different.

 

It looks the same mate.

Is the length the same and are the ends of the cable the same - same type and orientation of the nipple?
