Assuming you need to replace a burnt out tail light bulb on your 2009 VW CC:
To change the tail light bulb on your 2009 VW CC, first open the trunk and locate the two screws that hold the taillight assembly in place. Remove these screws with a Phillips head screwdriver and pull the taillight assembly away from the car. Next, twist the black power connector counterclockwise to release it from the socket. Then, press in on the tab at the base of the socket and twist it counterclockwise before pulling it out of the housing. At this point, you should be able to remove the old bulb and insert a new one. Be sure to consult your owner’s manual for specific instructions on what type of replacement bulbs to use. Finally, reverse these steps to reassemble everything and test your new tail light by turning on your headlights.
