...courtesy lights won't? on when the door is opened but work manually. However the engine won't start a message appears on the MMI saying unless the car is started in 3 mins it will shut down. I wait about 5 mins and then the car starts, On stopping the courtesy fog lights go off but the sides remian on??? (I keep them on auto) but they can be turned off manually? I changed the remote battery but this didn't help anyone any idea where the problem might be. Could it simply be a problem with the remote control?
