Help battery problem on c6 2007
I used my car 2 days ago but tonight when I tried to start it it had a dead battery. It is an A6 not manual. I noticed I didn't have it in park although the parking brake was set. Would this wear the bat down. I had a hard time jumping it but it finally came to life. The top would not go down (with the motor running) for about 20 minutes. The bat is showing 13.8 volts now. Any ideas on what happened?
Thanks

The RAP timer should shut off accessories (primarily the radio), but he didn't have the car in Park, so the computers never shut off. That's what pulled his battery down. Automatics must be in Park when shut down to cause the computers to go into low power sleep mode. If you don't shut off in Park, the computers will continue to draw 2 to 3 amps until the battery is dead.

Always park, in PARK. Get a Battery Tender, use it when the car is going to sit for more than a day or two, and you will have no further problems with the battery.

If your engine is running, the volt meter is only showing you the voltage of your charging system since the alternator is providing power to the system. To check the battery voltage, shut down the engine and hold down the bottom of the start switch to put it in accessory mode, then check the voltmeter.

Thanks guys. I promise never to leave it unless it is in park. The car has started up every time now but I,ve got to check why the rear view mirrors always go to the ground now, Every thing else works fine. Thanks again for all your advice

If you have 3LT and subsequently memory, the sideview mirror location (I think that is what you mean) is part of the memory settings. Just get the mirrors where you want them and press and hold the memory button (either 1 or 2 to correspond with which fob you are using to set them and you should be good to go the next time you get in the car.
