The tailgate lock on a Citroen C4 is controlled electronically, like many of the C4's other components. If the tailgate lock becomes faulty, it may unlock at unwanted times or fail to lock at all times. A faulty tailgate lock may also result in the lock not being as secure as it once was. Replacing the tailgate locking unit with a new locking mechanism can solve a majority of tailgate lock problems on the Citroen C4.
