Alarm Randomly setting off

[Gillieeric]

Hi, my 2017 Q7 alarm randomly sets off. It’s been like this over a week and it’s driving me mad because I can’t solve the issue. The car battery seems strong and has never let me down ! I’ve looked all over internet for solutions, none seem to work.

has anyone experienced this and solved the issue? 
Thanks

Theres not a fly inside the car? 

Have you had a diagnostic check to see if any fault codes flag up? 

[Gillieeric]

Hi, no fly or anything on diagnostics?!  
Ive got it booked in with Audi on Monday but it’s driving me mad and I need a quicker solution. I’m paranoid about parking anywhere now, I’ve even developed alarm tinnitus ! 
Thanks for replying though

Is there a switch that allows you to lock the car without setting the alarm as a short term solution?

[Gillieeric]

Hi No there’s nothing there 🤷‍♀️

thanks though 

[cliffcoggin]

That surprises me. I had such a switch in my 2007 A3 so I expected your modern car to be better equipped.

[Gillieeric]

I know all the threads and videos on YT show the button on DS door, but no there’s only a red reflector light there !

That's very odd. I recall it was a long time before I found the switches in mine, (one for no alarm and one for leaving a pet inside,) because the handbook diagram was unclear. Unfortunately I don't now recall the exact location and I no longer have the car for reference. They may even have been on the near side door which of course would be the driver's door in Germany.

Did you find out what the problem was? My alarm randomly goes off too.

[cliffcoggin]

Lee, you wii not get a reply from Gillian as she has not returned to the forum since 20th November.

I changed the key fob battery and ever since that my alarm  randomly goes off. Took it to the dealership for a Diagnostic check and it came back as attempted theft but not 💯 sure will need to do further checks 

[Gillieeric]

Hi, I took to my local garage and the computer showed fault on alarm sensor. So the reason it kept going off was to tell me the car was not locked. 
So he changed the alarm sensor, to the pretty tune of £350, but at least my tinnitus has gone.
