I can shut the trunk and it looks shut but all you have to do is pull it up and anyone can get into it. If the car is locked and the trunk is pulled open the alarm system will go off. The button on the interior of the car to open the trunk works and it sounds like the trunk is being unlocked.
My car is a 2003 Jetta 1.8T and the trunk will not lock shut. Parts needed? on 2003 Volkswagen Jetta
