Hi,
My car has recently been fixed after being in an accident. Now when i lock the car, the 4 indicators lights do not flash and the red LED on the doors do not flash. The alarm is not being activated. When i unlock the car the 4 indicator lights flash and the doors unlock as per normal.

The garage will not admit fault and say i need to take it to Audi garage and my insurance will not pay up unless Audi say it was related to the accident!! So theres a chance i will be £118 out of pocket just for a diagnostics.

Is there anything i should suggest to the garage, or anything i can do myself to diagnose/rectify this. Any advice would be much appreciated.

Thanks in advance.

 

Does the alarm activate if you use the key in the drivers side to lock the vehicle? That will confirm if it's an alarm issue or a remote control issue.

Probably need to check the coding for adaptation Channel 10 on Central Module Comfort System (#46).

 

Thanks for a quick response a4audi4fun!!

The alarm does not activate even when locking doors manually.
Just took car to a local garage who has diagnostics. The following error appears:

01134 Alarm Horn - H12 No communication.

Does this mean the horn is defective?
Would/could this occur in an accident when i have been hit from behind and shunted into the car in front?
Ive had front and rear bumpers replaced, bonnet and boot have been re sprayed and knocked out, a new radiator. The car alarm was working perfect before the garage started working on it.

Does anybody know how much it may cost to have the alarm horn replaced?

Thanks again!

 

The alarm horn is somewhere in the right rear of the vehicle (least that's where it is on my A4). I suspect either the connector got dislodged during the repair or the "siren" was actually damaged as part of your accident.

Sorry don't have any other ideas.

 

Thank you very much, i will get my local mechanic to look at it.

 

Thanks, i have mentioned this to the mechanic but he says that the horn may be under the 'skuttle panel'? Is this correct?

Also when i called audi for a price on a alarm horn one said £25 and the other dealer said only can get alarm siren with a control unit for £85. . . .

I dont know which dealer to trust.
