What causes the dashboard lights on an Audi 80 to flicker?

I've noticed that the dashboard lights on my Audi 80 flicker intermittently while driving. What could be the cause of this issue?

The most common cause of flickering dashboard lights on an Audi 80 is a weak or faulty alternator. It is responsible for charging the car's battery and providing power to all of the electrical components, including the lights. It may need to be replaced if it is not functioning properly.

Another possible cause of flickering dashboard lights could be loose or corroded battery terminals. Over time, these connections can become rusted or loose, resulting in an unreliable power supply to the lights. Check and clean the terminals, or have them replaced if necessary.
