Alarm service required
Discussion
Diagnosed as failed alarm sounder, tucked behind the nearside rear wheel arch liner. After 8 years, the internal battery had leaked, and the acid had destroyed some tracks of the printed circuit board (I cut it open to confirm). Lots of info on the Volvo forum. System reset as soon as the new unit fitted. Good service from Aston Martin Bits. Easy to change in 15 minutes max. using instructions from 6speed online.

a bump to this thread to see if any new information exists.
I need to replace the alarm sounder (Aston part 4G43-37-10655 / FoMoCo part ALARM SIREN 6G9N-19G229-DE ) on my DB9. There is great information on the replacement task, but not so much on the sourcing of the part. It seems this was a very common part on a number of vehicles other than Astons, including Volvos and Mazdas, but is now obsolete, so only to be found at a high price from places like astonmartinbits, or second hand on ebay. Given the propensity of these units to fail, buying second hand does not seem like a smart option, but..I would have thought there would be a grey market replacement or similar by now. What do all those Mazda 6 owners do when this part fails on their vehicles?
Anyone have any new information to add?

Just picked up this thread as i am confused by the replacement part too - as there seems to be a number of parts listed on e.g. Scuderia, which vary massively in price. Local dealer said the original part went out of production, hence huge cost/delays to get, but a newer version had now been produced.
The two part numbers listed for the 2006 DB(, with inclination sensor, are
4G43-37-10246 (your one) £660+
BG43-37-11254 £210
Did you ever get yours sorted out?

My V8V is now 18, so I thought due for a second new sounder. I purchased a s/h 2015 unit from a Land Rover, and tested it on my car to confirm functionality - all good. I then dismantled it intending to change the internal battery before it leaked and destroyed the circuit board, as happened with mine the first time. To my surprise, I found the battery not located on the circuit board, but in a separate clip on the inside of the casing. Moreover, it consisted of two AAA size NiCad cells (2.4v total) packaged together, and connected to the board by wires.
I conclude that the design was changed to obviate the leakage problem. Best to open and check battery type before buying a replacement. I have seen 2,4 and 5 cells in posts and vids.
