On VWs trunk light may need to have headlights on to operate.
Break lights come on when you step on the break, they do not come on when the head lights are turned on.
They are burned out.
You may have a blown fuse.
my head lights wont come on ,,all other lights work ,,no head lights
If by 'controller' you mean the switch that makes the brake lights come on, it is not in the trunk. It is located underneath the dashboard, next to the brake pedal.
The latch should be adjustable-it's not catching.
Check and see if the interior lights come on when you open each door. open one if lights come on shut it and wait for the lights to go off and then open another until you open all the doors. if the lights don't come on with one of the doors it will be a bad door switch on that door. if lights come on on all doors it may be the trunk. check and see if you have a trunk open warning displayed on the information center on the instrument panel. if so the car thinks the trunk is open and alarm won't set.
out of gas prbably
You need to replace the bulb in your lights. The dim lights and bright lights have different bulbs.
there is a short in the relay for the head lights
Have you checked the fuses?
The switch in the trunk that is on the locking mechanism itself needs adjusted or if you don't have time to mess with it really just disconnect the wire going to it the trunk light wont come on until you hook it back up though that little light on the dash will run your battery dead because its really telling you that the big one in the trunk is on too.
