2009 GTS alarm won't engage
Looking for some advice.
I had to park on a quite steep hill on Saturday, maybe 20% gradient, noise down. When I locked the car using the buttons on the fob it made a second long beep about 10 seconds after the normal beep that indicates the alarm is set. I assumed that the steep hill had tripped the tow sensor and thought nothing of it. Every since then I've been getting the same behavior every time I lock the car, over the course of about 2 days now.
Is this likely to be the incline sensor? The dealer thinks it may not have reset properly and that it might rectify itself over the course of a few days.
