This happened to me with my BMW G01 X3, the seat mat sensor was not functioning properly and kept saying there was no one in the seat and airbag will not deploy. Odds are the dealer won’t look at that first, but I would request it.
I had a similar problem on my Ice Macan, when a pasanger got out of the car and I was continuing my travel the car would constantly beep because the passenger seat belt was not fastened. It was clearly a seat sensor problem but the Porsche dealership would not fix it as it was only a neucence.
Just to update , my dealership scanned the car and could not find anything wrong , I did however find a sensitivity setting in PCM and now it happens infrequently.
Service advisor said there is a sensor in the steering wheel , I can not fathom where ..
That's interesting. Could you point out how to get to the sensitivity setting in the PCM? I don't think I've ever seen anything like that before.
The sensor in the steering wheel is capacitive, so it detects if you touch anywhere on it. It's to make sure people don't turn on innodrive and then go completely hands free.
