Boot not locking down tight

[pdrisc]

Hi

 

The boot on my L&K has developed an issue where its not clamping tight. It appears to be shut but as you drive away the lid lifts slightly and the warning symbol comes on.

 

There used to be a clamping system on my old mk2 which played up before. Is this a similar fault or has anyone else seen this issue? Car is a 67 plate.

My 2017 SE Executive has the same problem, albeit intermittently. I don't know the solution!
