Went to start the car on weds night, having not driven in for nine hours. Interior light not left on or headlights........put key in, depressed clutch, selected neutral and pressed start button. Dashboard lit up like a Christmas tree and all sort of warning lights going on and off, and just a clicking from the starter motor.

Any ideas what it could be as i cannot see how a battery could drain given that i use this car every day?

Went away for the weekend in other car, so have just put Aston on trickle this am to see what happens.

Did you do the battery kill/reconnect? Sometimes rectifies this.

Could be the well-known (but should have been sorted) door module (the courtesy light in the door to illuminate the kerb stays on, draining the battery). On a DB9 (though I think it is different on an AMV8), the headlights turn themselves off if you leave them on low beam but not high beam (I've done that...).

Also use "every day" doesn't always help. If you do a quick trip, with headlights, heated seats, heated front & rear screens, radio, etc., then the battery drain is actually more than the car generates in that short period and you'll slowly lose power.

Weird problem, car is fine now so not sure what happened!

Left the car on conditioner all day, then pressed the battery on/off switched located in the small hole located on the bulkhead behind the drivers seat.

Car started back up fine.

weird confused
