Audi A3 8p 2009 electrical problem

[wbania1]

Hello, I bought an Audi and I have a problem, while driving, from time to time, the cluster illumination goes out, the air vent turns off, and the high beams and turn signals stop working. This happens on average every 5-10 minutes and lasts 2-3 seconds. It looks like maybe the can line is getting jammed, losing communication, I don't know, I didn't check for errors. Does anyone have an idea what it could be?
