Audi Repair: a4 taillight, audifans, plastic keys

Question
2003 A4 1.8  How do you remove the rear lens to change the  tail light bulb?

Answer
You can get to the rear of the lens by removing a cover inside the trunk, remove the nuts on the inside and then there are ball shaped plastic keys holding the lens in place, careful not to break this off.  The procedure is described on some of the forums like audiworld and audifans with pictures, let me know if you cannot find this and I will look up the link.  Jan
