the emergency triangle button, stays ON (lit) if there is something draining the battery-audi made it that way.

I recommend to put a test lamp, or a bulb accross the positive battery terminal so see how much drain you got:something big or something small of less consumption.

Also you can start pulling out fuses with the car locked and the hood open to see when the drain goes away by looking at the bulb that you pt accross the battery terminal.

keep removng fuses until you determine which component is casing the drain.

is there an aftermarket handsfree instaled?

[ominimicu]

0.05 a is the max perimted..for alarms and other sutff. So yes, something stays on in the Mm system. like bobby said, any handsfree? aftermarket stereo? chargers etc?

did you own vcds?when yes then you can make diag on it,for see what components drain your batt. flat.

Any water in car? I had more than two cars in the last couple of years that had drain from the factory radio amp in the trunk. The amp had signs of water. Disconnected the factory amp and no more drain. Customer had to repair rear leak and new amp.
