For the last month i haven't been able to get the bonnet to lock. Had a look yesterday and can't work out why it's not clicking down. Raised the lock as high as it can go, still no luck - as i cant see what is happening when i push the bonnet down I'm not even sure what (if anything) is broken. Any ideas?!


On a different note - finally decided to take the RH rocker cover off to polish, the end result wasn't bad!

What did you use to polish the rocker cover, it looks pretty good from the photos.

Try using something like a screw driver to see what happens when the bonnet closes and the metal bit on the bonnet goes into the catch. I would expect the locking cam to mover over to hold the screw driver. Something must then lock to hold the cam in place. That something is what's moved when you pull on the bonnet release cable. It might be a broken spring or gummed up works.

Happy New Year!

Might sound obvious but have you pushed the release lever (inside the car) all the way forward? Mine sticks in the unlocked position causing the bonnet to fail to latch.

after you have repared it fit a piece of fishing line or string to the catch and locate the other end on the pannel below the windscreen on the nearside so in an emergency if the main cable brakes you can grab the line which will open the bonnet .

Thanks for the replies guys!

Myph - i saw a topic a while back. Took the cover off, used a de-greaser and cloth to get most of the muck off, then a drill and abrasive brush drill bit. Once done i used wet & dry paper working through the different numbers so i ended up with clean finish with as few scratches on the cover. If you follow the link below there is a link to a polishing kit i bought, used this and finished it off with a few coats of engine lacquer (unfortunately i was over enthusiastic and on the last coat got too close which caused a few drips...but still looks good). Link below:

With the lock, took a screwdriver to it this morning and even with my 14 stone weight - couldn't get the screwdriver to lock, the spring seems to be extremely tight!? Will try tomorrow to see if the release lever is fully pushed forward but the top spring (not the spring for the release lever) is tight, might be a case of replacing this - have no idea why tho, use to pop the bonnet regualy each month with no problem.

Like the idea of the fishing line, will do this once fixed!

When you push the screw driver onto the clock the locking arm should close quite easily. If you're pushing down hard then something in
the mechanism is jammed and needs to be found and freed. Sorry to be vague!

Got round to fixing the lock this weekend. Bonnet cable wire seems to have stretched and the lock itself keeps jamming even tho its been taken off and cleaned. So just ordered some new parts, simple job to do?

Under the dilution that I would need to take the old lock off - put the new one on. Cut away at the silicon holding the cable water tight to the engine bay, then pull the old cable through but attaching it to the new on with some string before hand. Am I correct in thinking its that simple?
