Hello, i have problem with my Audi A6 C6 2005year, problem is dashpanel flashing. Panel starts flash, when outside is dark/night. It starts flash, when remove the key and mid console stop lighting, then panel randomly turns on/off or flashing all time. Locked car do it same. Only way to stop it, is unpluging battery. Any have idea, what is wrong with my car?

 

Today, i see, that the panel is flashing in day light too, he starts, when pull out the key and wait 10sec.
