Bonnet won't lock

[firewallguy]

Checked the oil this morning, closed the bonnet, and then turned the knob too far or something when locking the bonnet and now the knob won't turn much or lock the bonnet

The pastic things on the ends of the rods were broken anyway but it did at least keep the bonnet down.

Ok, looks like I will find all the answers I need in this thread:

The knob is attached to a shaft, which has a groove in it. I think it attached by a fine, Allen grub-screw.

The locking position of the system is controlled by a collar which has a larger Allen grub-screw. The full range of the shaft, which attaches to the two release pullrods, passes from fully open, through a central, locked position to a fully open position again. This allows you to decide whether you want to open the bonnet by turning the knob Clockwise or not.



I would think that either your knob is loose – and will not turn the shaft
OR
The sprung ball-bearing, which is located in the shaft groove, is jammed. If this is the case then judicious application of the life-saving WD40 and a bradawl should free the system.

I had a hard job writing that without laughing – especially when I found this picture in the directory pertaining to the subject

Ha ha, that's funny :-)

Anyway, when I got round to looking at the knob I found that the big screw on the collar was butting up against a chassis tube, I just needed to pull it out slightly so it would turn fully round and go back to its original position, locking and unlocking as before.
