2014 DB9 electrical problems after winter storage
Glad this was helpful. If I didn’t notice the odd
behavior of the mirror I would still be trying to convince myself it was the AUU.
I am unsure what to do next. I do have problems with my driver door glass not always dropping enough to clear the top, despite many attempts to reset it. I am tempted to replace both modules if I can buy them right. Pricing seems to vary quite a bit between vendors. I have a call in to my dealer to see about flashing new modules.

I am no expert on this whatsoever, but it does seem that I can buy the DB9 door modules new. Prices seem to be all over the place.
My understanding is the only way to get them to work without a dealer flash is if they come from the exact same car (in my case a DB9.2 Volante). I have no idea if the new modules you can buy from the various parts suppliers have any software flash on them at all.
There are a few Aston experts lurking here. Maybe they could chime in on this issue.

Thanks. Just did that. Module prices seem almost too good to be true.
You should be able to swap without programming if they're verified to come from the *exact* same specification of car and swapping like for like with old style or new pektron. Changing type always results in a vehicle CCF edit and reflash of the CEM and door modules. Also, ordering from GB won't work for this since the driver/passenger modules are swapped left to right. The result will be the windows and mirrors will operate inverted. Undesirable. I ran into this with mine and the fix was a flash and VIN relearn with my AMDS.
Also, make sure you have a good history on any modules. Check VINs online for the vehicle salvage reason. Reject any ebay listings where you find flood damage. You'd be shocked how many there are.

Door module
I'm sending mine off to be repaired. Hopefully it's successful and I'll update the results when I get it back. I couldn't find an exact match used one and Aston Bits said the new ones have to be replaced in pairs and require AMDS flashing. It's $250 for the repair so that's obviously a bargain if it works out.

I sent it to Module Experts in Jacksonville, FL. They were confident they could repair it. Of course, that's pending inspection upon receipt. They were easy to talk to and seem knowledgeable.
Off topic but the reason for this was that Floirda had several big storms that caused historic floor during the period where these cars were popular like Storm Debby (2012) and Irma 2017, and then extreme rainfall (1 in a 1000 years) in 2023. So many cars during these periods got ruined so they got salvaged and broken down for parts.
option. I ordered a new module from AstonMartinbits and they canceled my order saying they don’t have any. I have been calling my (semi local) dealer in Boston for days now and no return calls from anyone in service there.
I don’t know of any independent shops with AMDS in Massachusetts, Connecticut, or Rhode Island……anyone?
Let me know how it goes. It may be my only

Astonmartinbits just informed me (just as you reported) that the Pektron modules have been discontinued and now superseded with new versions that much like the older cars must be replaced in pairs at a very high cost and programmed by the dealer.
We are looking at many thousands in parts, labor and programming because of this, so there may be a good market for repair if they can figure it out!
