Just a warning guys - i had the same problem, no matter how hard i tugged the lever the bonnet wouldn't budge..
I had to get somebody to fiddle with the lever while i lifted the bonnet to get it open everytime
Snapped two levers over the year it was like this, the first lever i got a replacement from ebay for around £5 posted
When i snapped it the second time i took it into renault and asked for a replacement cable and lever..
The plastic lever alone cost £14!
In total cost me
£160 and
they left the bonnet cable hanging out of the arch!!
Result:
When i open the bonnet now i only have to move the lever half a cm and it feels like a new car though
