Hi, I’m new to the 992 Turbo. When I exit my car, and lock the car. The alarm goes off a few seconds to a minute later. Am I doing something wrong?

2021 TTS - no updates to PCM that i know of or that are needed:

As far as i know it should not do that - it doesn't on mine - just a beep & lights then done - see how others respond

Do you have anything plugged into the OBD2 port?

I do have one of those car insurance thingies in there. I drove it last night and it was fine..

dumb question but am I not shutting this car off properly. I do use Bluetooth with my phone too for audio.

In my experience, a dongle plugged in to the OBD port caused random alarms. Unplug it for a few days and see if your problem goes away. Should not be related to bluetooth.
And you are driving a TTS and want your insurance company to see how fast you drive?? SMH

It was happening before too, but I will try it. And yes I do; I don’t drive very fast anyways. Need my discount

You are doing nothing wrong, Porsche has had some issue with the interior sensor going bad. After you exit the car and start to walk away the sensor activates the alarm.

The test is simple. While in the car after you turn everything off BUT before opening any doors there is a pop up on the PCM screen that asks if you want to leave interior monitoring on. Nobody pays any attention to the and just exit the car which turns it on. In your case when that pop up appears select Turn Interior Monitoring Off then exit.

If the alarm doesn't go off, you just diagnosed your issue. You have to select that off position each time before it defaults to off but by then your dealer will have replaced the sensor.

Let me know if that worked for you.
