Cayenne S 2005 with Auto Headlights. This is a feature I have always used and loved it...but now it doesn't work and my Porsche Dealer was not able to fix it. What happens now is that the lights always stay on when on Auto even in the sunlight.

How they are supposed to work, and always have until recently, is the headlights come on when its dark out and turn off when its light out. It is great for driving through long tunnels or parking garages.

My Porsche dealer here in NYC said that since my car has not thrown an error message so they can't troubleshoot it. Then the service manager tried to explain to me that they were working fine since the lights come on and started to descibe what are "day time running lights" which clearly the Auto Light option is not day time running lights...strange that he would try to sell me that story.

Anyway, any idea of how I can troubleshoot this myself? Is there a sensor that needs to be replaced that senses the ambiant light?

Thank you
