2016 Vauxhall Cascada boot won't close

You pulled the boot cover and sprayed the lock assembly with WD40 or similar might help but probably need new lock

Thanks for your reply, I've tried that but didn't work. The boot opens first time every time its on the closing that's the Problem. Do you still think new lock if it opens every time.

Could still possibly be an internal fault on lock if boot adjustment is o.k , Try this , open a window or a door and try closing . A long shot but on some cars the build up of air pressure inside the car on closing can sometimes affect closing .
