Hello, I have recently purchased a 2011 40d what a fantastic machine my first X5. One of the options it has is S4NCA (additional heating/ventilation) what does this mean ? I would really like to have the auxiliary heating option but only seem to have the cold ventilation on timer. Any ideas from you ...
