Have you managed to see what it's pulling yet? Found this in another thread..

"Thanks for the responce. 33 ma with doors and decklid closed. Alarm not armed.'

"33 ma is all fine. "

And more..


I've checked the battery drain on my 04 Coupe which should be representative of what you should be getting. I do have an aftermarket head unit/ipod setup but that should have drain to the factory system.
The current drain is around 114mA with the car locked i.e. alarm armed. There are odd peaks to 156mA, presumable the ultrasonic scanning periodically. So assuming you have a fully charged stock battery which has a capacity of 74Ah and taking the worst case 156mA drain you should get:

74/0.156 = 474 hours or 474/24 = 19.75 days until the battery is flat.

If you take the 114nA figure you get around 27 days.

And 180 has confirmed himself.. :-)

By coincidence I have just checked the parasitic drain on my battery.
Unlocked it averaged 15 mA and locked it jumped back and forth between 15 mA and 20 mA. The 15 mA reading flickered between 13 and 16 mA. The 20 mA reading flickered between 21 and 19 mA.


If your exceeding these numbers, start pulling fuses to see what circut is pulling the amps and that will at least give you the culprit.
