over the winter in Portland Or we had our low mileage and well cared for A6 fail to start with a dead battery. it always starts and charges fine after jump starting. a few weeks later it happens again. Were at 5 times in 12 months. I replaced the 6+ year old battery last month on advice from my pro mechanic but it happened again today even though I drove the car yesterday. Again nothing was left on. What computers are screwing up causing this key-off load? I haven't looked up service bulletins yet... just starting trouble shooting.

email me @ david@audipoly.com if you have maint history info. thanks awl. Dave
