I went out to start my Treg and found the dashboard lights lit (see pic). The car was otherwise was dark, no dome lights lit up when I opened the door. I put the key in and turned and nothing happened. No crank, nothing at all. It also wouldn't release the key fob from the dashboard. So I put a charger on the underhood terminals. The dash lights went out and I was able to get the key out. After several hours the charger showed a full charge. The same dash lights came back on, but nothing else works, and it still won't crank. Also, the key won't release again. The battery is only one year old. It's a 2013 V6. With no power, I can't scan anything. Thoughts?

Agree.... doesn't make sense that your battery is full but you can't even connect a scanner.
Leave the charger on the posts and try hooking up your VCDS with the egg still on life support.

If your battery is only a year old and was coded in when installed, it could be possible you have a parasitic draw on the battery that caused it to go dead.
Give the thread in the link below a read. It seems other members have run into this on theirs. They mention a few possible fixes, but again you need to find out why the battery went dead in the first place.

I decided not to trust the charger's "word" that the battery was full and I put a jump start pack on the terminals. That got the engine started so now I guess I have to look for a parasitic draw.
Find a place that can load test that battery. Not a digital tester, they are for pedants. Find a shop that has analog tester. Make sure the battery is fully charged before the test. Perform 3 consecutive load tests using half of CCA for 15 sec. Get the results, report back.
