My alarm doesn't work
 

The lights just flash, Vag Com says:

00956 - Key 2
09-00 - Adaptation Limit Surpassed
01134 - Alarm Horn (H12)
76-00 - Terminal 30 missing
01134 - Alarm Horn (H12)
49-00 - No Communications

So where is this alarm horn? +++

In the boot, behind the trim on the passenger side roughly below the antenna.

^^^^ Yup, exactly what he said....

Thanks I will have a look +++

mine has never worked from the day i bought it. does the same lights flash but no sound ! if you get yours working then let me know how ?

Will do, mine hasn't either. Will the alarm horn from a 96 A8 or a 98 A8 work in my 2001 S8 to test before I ordered a new one? I don't have the A8's here but I will go look at the S8 now.

These alarms have an internal battery which eventually runs down, but they're sealed units.

I replaced the S4 one with an A8 unit and it works a treat - you can get them from A8parts of course +++

Thanks Clive, strange everything coming at once for the S8. Just had to renew the insurance (feels like I did it only a few months ago) and its ££££'s new tyres £1k+, park sensor, road tax £210, gearbox and new track rod end, four wheel alignment what the heck is next? :rolleyes:

I couldn't find it! Could someone get a picture please?

Maybe its missing - That would explain the silence.... :p

One facelift alarm horn:
