Codes that have been plaguing me for a while....Maestro inside.

Hey Guys, so I haven't been able to figure this one out. I only get these codes on start up.

If I clear them and continue on my drive, the codes don't come back for the entire journey, until I shut the car off, and start it up again.

Here are the codes:

Trouble code 1 ; P0562 System Voltage Low Voltage
Trouble code 2 ; P0037 O2 Sensor Heater Contr. Circ.(Bank1(1)Sensor 2) Low
Trouble code 3 ; P0351 Ignition Coil A Primary/secondary Circuit
Trouble code 4 ; P0353 Ignition Coil C Primary/secondary Circuit
Trouble code 5 ; P0352 Ignition Coil B Primary/secondary Circuit
Trouble code 6 ; P0354 Ignition Coil D Primary/secondary Circuit

Keep in mind I had the ignition wiring replaced with OEM new by a certified VW-Audi master tech at an independent shop. Coilpacks are 1 year old TFSI with IE adapters. Spark plugs are NGK-PFR7B gapped to 0.025".

Any insight would help, thanks!

From that possible grounding issue if it affects all 4. I would check the ground and make sure that there is bare metal to metal contact. If it was one issue it would show up. Just look over the wiring.
