VAG vehicles always seem to have codes that trigger off one event and just stay there.

Code 49472 : lost communication with control module.
Code 01305 : databus infotainment-no signal/communication

See if you can pull up the freeze frame data for each code, you want to look at the number of times the event was triggered and if it coincides with a low voltage event. They are both codes that can be set by a loose connection to the stereo system or if it has an after market audio system.
