Battery Problem?
I have an 06 A6 Coupe. I have had the car 10 months with 1200 miles. Battery was dead last night. My dashboard put on some light show along with noises from all over the car. I had the car jumped and everything seems normal. I went for a 40 minute drive and the system was showing 14.3 volts. After I got home I waited about 10 minutes and using Acc. switch I got a reading of 11.8 volts. No drop when I turned on the lights. I am preparing for another jump this time I backed the car into the garage. Is the 11.8 indicative of a bad battery or is there something causing a drain. A forum member mentioned to have the door regulators checked and BCM flash. My main concern now is the 11.8 reading any other ideas?

Suggestions Needed Please
What should be my next step? After a jump yesterday and a 40 minute ride (about 4 hrs. later) I checked my volts via Acc. mode where it showed 11.8. The car started right up, if I did'nt have the previously mentioned dead battery I would not have noticed anything peculiar or even check these readings. This morning before starting, I checked the voltage and it showed 11.3, again if I would'nt have looked the start was normal. I am planning to bring the car in for a check on Tuesday. Besides having the battery checked, is there anything else that I could mention for them to check. I value the forums suggestions greatly because I seem to get the right answers all the time. Thanks for any help.

afraid you and I have batteries no longer batt'n. I wouldnt reflash anything yet. Go with another battery first. 11.8 after driving for 40 min would indicate that the battery is not holding a charge. I looked over my bat and am seeing some(little) acid leaking out and running down the side. You might want to check yours too.
If your post is correct 10 months and 1200 miles would mean you should have your battery on a trickle charger.
