Hi guys - so I have a Mk6 Golf and I have a problem with the petrol flap not locking.

I've taken the flap out and locked/unlocked the car and can see the locking pin appearing at the end of the tube it's housed in but that's as far as it travels. It needs to come out another inch or so to actually lock the petrol flap.

It all seems to be working but doesn't travel far enough to lock the cap.

Any ideas?
