I've had a '05 DB9 for about 2 years and haven't driven it much at all. Today I drove it for 200 miles and it was great. Afterwards I washed it and immediately after washing it when I started it up the headlamp washers came out and dumped the entire contents of the washer bottle. I opened the hood and found that the fuse box lid was off and I assumed some water must have done something. I dried it with an electric blower and refilled the washer bottle. Now when I turn the car off it thinks the key is still in the ignition and one of the relay's keeps clicking w/the engine light on the dash flickering.
I found the relay that was clicking and removed it. I even swapped it with one of the other relays that was the same, but the clicking came back and same issue.
I've attached a pic that show which relay it is:
The area circled in RED is the relay that was clicking
The ares circled in Orange is a relay I had to take out in order to get hold of the clicking one
I have left both relays out and attached the trickle charger for the night.
I would disconnect the battery and let it sit for 20 minutes or so. Not sure what's wrong, but I've found that doing a hard reset of the power is a good way to start fresh.
After sitting all night I re-installed the relays and it seems to be fine. A code scan turned up a ton of codes P1797, P0115, P0148, P0100, U2011, P0001U1 E49, P3 A000, P1 A41, P1 A21, B0F30, P1 A22, U1 F11, U1 E11, C2C31,and more including one that said headlamp washer relay open or bad ground
After clearing codes everything seems fine. Prior to this I had the C2C31 inclinator code and will fix that this month - but everything else seems ok.

Thanks for being a resource of information here.
Hello. Did you end up fixing the C2C31 code? I am having the same code, and the "alarm system service required" message... Thanks.
