Audi Electrical Issues
Recently my 2016 A4 has been experiencing some odd electrical issues when driving. At random points during my trips, warning lights on my dash will light up for a brief time and disappear again. Shortly after the lights disappear, all power will be cut off from the car. I have been disconnecting the battery terminals and reconnecting them after a few minutes in order to fix this. Each time the car returns to normal with no warning lights on display. I should also mention that I have not seen any performance decrease in the car overall, except in the brief moments when the warning lights appear. Any advice is welcome.

Scan for DTCs. Evaluate the charging system by looking at blocks 14-22 in address 19 (CAN Gateway). You need some factual numbers. You're going to need an Audi capable scan tool for this, not some generic drivetrain OBD scanner. What warning/lights are coming on?
