Audi A6 battery drains when car is left idle for 2 days?
Audi A6, 2L, 2002 model. I have a new battery, when I drive my car every day I have no issues, leave it idle for 2 days and it will not start. All looks well (good battery, alternator etc) except for a 300mA drain when idle. I have traced it to the fuse that protects the console, radio etc., and now disconnected the radio. Drain is now at 75mA when idle, which still drains the battery after 2 days idle.
I had a similar probably with my 2006 A6, take it to the dealer because there's probably something wrong with the electrical circuits thats controlling the battery and everything else. Have the dealer look at it.
the alternator might not be undercharging the battery its charging but very little of it, and why is your car idling for 2 days ???
