What causes the dashboard lights to flicker in an Audi A7?

I noticed that the dashboard lights in my Audi A7 have been flickering when I start the car. It only lasts for a few seconds but it's starting to worry me. What could be the cause of this and is it something I should be concerned about?

This could be caused by a weak battery. As the car starts up, it puts a strain on the battery and the lights may flicker briefly. It's best to have your battery checked to ensure it's at full capacity.

Another potential cause could be a faulty alternator. If the alternator is not properly charging the battery, it could cause the lights to flicker. It's important to have this checked and repaired if necessary to avoid further damage to your car.

In some cases, the flickering lights could be a sign of a bigger electrical issue. It's best to have a professional mechanic take a look and diagnose the problem to prevent any potential safety hazards.
