Obviously this is a security issue so please respond by pm. My cable is broken but I don't even know if it's standard fit, no mention any where on the web of it but as mentioned its a security issue. Tried looking on Simon's spare parts but struggling any help, please
I would be surprised if it is not standard fit personally.
There are two cables involved with the bonnet release mechanism. The one starting from under the dash by your left leg which releases the bonnet catch itself, plus another cable operated by the headlamp mechanism which stops you opening the bonnet if the lights are up, by moving a pivoting bracket with a bent angled stop on the end against the release mechanism.
You can open the bonnet with a screwdriver from underneath, but not sure how much access you have with the front bumper on? Mine is only off at the moment as I am in the process of changing the radiator for one of Simon's sexy aluminium ones.
I have attached some photo's for clarity and hope this is of some help?
