MK8 Alarm issues?

Hey everyone,

Aside from the usual issues faced by many I get an unusual amount of anti theft alarms triggered on my MK8 Life.

The neighbours really aren’t amused. Anyone else had this before I go speaking with the dealer?

Do you have something in OBD port? I just check Erwin service portal.
They says if something external device trying connect to car when car is locked, alarm will activated

Hi Gio, I have a MK8 GTD and have also had 5 instances in 3 months of the alarm being activated incorrectly. The message I get is that ‘Activity was detected on the outside of the vehicle’. I asked the dealer about what would cause this and they reckoned someone trying a door handle when it was locked. This turned out to be absolute rubbish, like most of the info the dealership gives out. I’ve tried this myself many times without activating the alarm. I’ve had it go off 10 minutes after a 150 mile trip and also after being in our locked garage for 4 days without use, so cannot pinpoint anything there. The issue is still with the dealer to investigate but like most things, they just say it’s a software error! Considering the other software errors currently under investigation I guess this won’t get resolved anytime soon. Do mention it to your dealer though as the more people who do so might help to get a fix from VW. Fortunately for me, I haven’t upset the neighbours too much yet!

Do you have a dash cam (or other electrical accessory) fitted that’s hard wired? I’ve read of instances where a dash cam can cause excessive drain on a car’s battery when the car’s parked up if the dash cam is set to continually record in parking mode, and that could trigger your car’s alarm. Alternatively, your car battery may be defective - maybe worth getting it tested as it’s not unknown for a battery on a relatively new car to fail.

Thanks for this info Martin, really appreciated. Weirdly mine is saying an activation internally. Yes like you its tough to pinpoint it happening after any specific drives as some can be a few days parked some can be a few hours parked. Guess it’s time for a chat to the dealer. Not holding out too much hope either…

Great reply as I thought it was also battery drain!! I don’t have a dashcam but it does have a company car tracker on it. I had the company who installed it come out to check it was wired right to confirm this wasnt it. All was fine their side but will definitely investigate a possible faulty battery. Thanks for that idea.

Nothing in the OBD port as far as I am aware. The car has a tracker but this is just GPS and not telematics. Great shout though, appreciated!

Just an update in case anyone is having this problem. Car went in to the dealer 2 days ago. They claim to have done a software update that had interior monitoring updates so we will see. If this doesnt resolve it then they will be replacing the sensor units.

Car was also meant to have another update for the 91CM recall but VW put this on pause the morning it went in… not sure why though??
