I had automatic xenon lights in my two previous cars, the most recent being the f30 bmw 3 series. Driving through an underpass the lights would come on and once I'd exited would go off after a few seconds. With my mini the LED lights come on but take up to 2 or more minutes to turn off even after emerging into bright sunshine. Would have thought the bmw and mini systems were the same. I'm wondering if anyone else is experiencing the same thing. Is it simply a mini thing or could the sensors on my car be faulty.
