Can’t wait to try my Calix setup! At the moment there’s no chance as the house we’re in temporarily while we look for our permanent home doesn’t have a driveway
What a beautyGot the little car out of the garage today and drove it to Wheelbase (my local VW Audi specialist) for new Textar front discs and pads. My A2 has not been used for a couple of months, but started first time and drove flawlessly. It even passed its MOT without advisories!
Today was a good day....

I found these videos very useful:Last night I finally worked out how to read the current flow diagrams on Elsawin (I still don't know what the numbers refer to in the rectangular boxes though)....
I think it'll be a dead battery. I fitted a replacement (slightly higher capacity) Nimh battery on the outside of the alarm siren case, and connected it, by short wires, through a hole (drilled and sealed with silicone) direct to the old battery leads, once the duff battery had been snipped out, leaving enough lead to solder to.I found these videos very useful:
Thanks @Catnip64 Those videos are great, I now understand a lot more .I think it'll be a dead battery.

I used a junior hacksaw around the case join, to open it, and self amalgamating tape to seal it up.

Looks like I spoke too soon about my new A2 all working correctly, the alarm started sounding last night and after plugging it in to diagnostics and having a search on here it looked like it might be something to do with the backup battery in the siren. A replacement unit is around £80 but If...www.a2oc.net
If you go for s/h, ask seller for pic of the date code before buying. Look for the most recent, and consider replacing the battery, even if it is OK.Thanks @Catnip64 Those videos are great, I now understand a lot more .
@PlasticMac Thanks, I'd seen your great post about the alarm siren and thought it could be a duff battery loading the supply, so I got it opened and powered on the bench and it was still taking 110mA from a 12.5v supply, I cut the battery legs whilst watching the ammeter and there was no change, the battery less pcb was still sinking 100mA.
On inspection there were a few smd transistors and resistors around D1 that were discoloured with heat and dodgy looking so I think its a gonner
Thanks both for your help.
I owned a BMW 525d, E39 era 52 reg back in 2006 and that had bluetooth and a button on the steering wheel to take calls. That was cutting edge....learned that one of my A2s has factory Bluetooth.
I didn't even realize Bluetooth was even a thing back in '05, when my family had neither a mobile phone nor an Internet connection.
