01134 - Alarm Horn - No communications

[Stringster]

Getting the error code 01134 - Alarm Horn (H12) - 49-00 No communications.
Along with this, when the alram is triggered the indicators flash but no alarm.
Any advice on what to check ? I've only had time to check the connection to the siren in the boot so far - seems to be fine but still got error...

sounds like your alarm siren is kaput.......

if it's anything like on an A3, a new unit costrs around £80

Are new units main dealer or are there any other suppliers ? Guess I could also get one fom a breakers.
I'll have a ring around.

I have the same error
01134 - Alarm Horn (H12)
49-00 - No Communications

So what can be done to fix this?
