Hello fellow fanatics. I read a couple of times about a hidden menu in idrive to read coolant and or oil temperature. Does anyone know how to access this? Like I have got nothing to do while I drive around Gauteng, but I see oil temp on the analogue reader goes up a lot when traveling over 80 to 90 Khm and want to see actually what temp this is. I have a 2015 320i pre lci. Thank you
