01134 - Alarm Horn (H12) Fault Help please

**midge6** · 16-12-2008,12:16 PM

Hi guys, i got this result from a recent scan and i was hoping someone might point me in the right direction as to finding the actual fault - the car is an 2004 Audi A6 1.9Tdi Avant. I have cleared the fault a few times but it always comes back

All advice appreciated.
Many thanks

Midge.

Does the alarm sound when you set it off ?

Hi Kite - that was a quick reply thanks.

I have just tested it (Sitting inside while armed) and the alarm activated after i moved. The indicators started flashing and there was an audible sound from the rear of the car similar to what you might hear when lorries are reversing - there was nothing really loud or anything that sounded like an ordinary car horn. To be honest, i don't know what the alarm should sound like - i know, bit daft really...
Any ideas?
Many thanks
Midge.

Well your alarm works...........
Can't find that fault code on the Rosstech wiki.

Kite -

Sorry just remembered, a couple weeks ago the alarm went off and the indicators flashed but there was no sound – I guess this might be the intermittent fault?

Try scanning again and clearing the codes.

Hi,
Just done that and it is now clear, trouble is, i have done this before and it always comes back? A loose connection perhaps?
Many thanks
Midge.

Could be a loose connection somewhere !
Bloody intermittent faults

Too right! Nothing worse to take to a garage. Ah well, maybe some kind soul on this forum might be able to help.
Thanks anyway,

I agree - you have a connection issue and short of chasing the wiring to the alarm, I see no way to resolve it. A good starting place would be to trace and check all connectors related to the horn. It will not be fun! Intermittents never are! (Could be a loose pin, a bad crimp on a wire, corrosion in a connector .....)
