There are a few reasons why a Volkswagen blind spot mirror may not be working.

The mirror is damaged. If the mirror is cracked or broken, it will not be able to provide a clear view of the blind spot area.
The mirror is not connected properly. Check the wiring harness to make sure that the mirror is connected to the power supply.
The mirror is not receiving power. If the mirror is not receiving power, it will not work. Check the fuse box to make sure that the fuse for the mirror is not blown.
The mirror is not programmed properly. Some Volkswagen vehicles have blind spot mirrors that are programmed to deactivate when the turn signal is activated. If the mirror is not programmed properly, it may not work when you are turning.

If you have checked all of these possibilities and the mirror is still not working, you will need to take your vehicle to a Volkswagen dealer for service.
