2006 A6 Battery issues

[wmccann]

Hi,

Whenever I start my wife's A6 Avant it comes up with the battery warning symbol. When I go in to check it's level using the control panel it has maximum 1 bar on the scale. The car starts and if I check it again about 10-15 minutes later (driving during this period) it is back to about 60%, after another 5-10 mins it is 100%, then the next day same thing.

When last in for a service we told them about this and they came back with a "firmware" upgrade. this did not help and we are still getting the same issue.

Nothing is left on and I am at a loss. Anyway I checked the car with my vagcom and the following is what came up:

Any help appreciated as these codes are not on Rosstech.

Thanks,

Quiescent Current usually means current draw when something is not in use but it still has a power feed, in a car I would imagine it to mean when switched off and just powering the clock, alarm, idle ECUs etc...

Were these codes/dates after you went to the dealer?

Walter.
