Ok so we just bought a 5 last friday and we love it buuuttt.....I got a problem. Tonight was the first night I used the radio with the key in the ACC postion, and when I went to close up this red light now flashes. Its the red car with the key in the middle. Something about the immobilizer (s/p) system. It only flashes when I turn the 5 off, it goes away when I start it. What the hell did I just do?
