A6 Avant Le Mans 2010 Suffering from random alarms always inconveniently in the early hours of the morning. I borrowed VCDS from a friend and had a look. No alarm related fault codes, so it's a proper trigger. A list of alarm triggers shows 9. Intelligent siren. Maybe paranoid siren would be more appropriate. Does this sound like I need a new siren unit. If so can anyone advise on the Part No to order. Is there any further information I can get from VCDS to help fully identify the issue as the siren. If so where do I look, I'm obviously new to using it. Finally, if it i the siren is it behind the dash under the wipers on this model, or in the luggage area of the boot. Thanks.
