I am sure this question has been asked a million times, but can't seem to find the correct answer. I just bought a 2012 E Class SE Saloon. When I turn the engine off the headlamps stay on and the LED lights on the bottom of the front bumper come on. They then time off after a couple minutes. Other than in this situation the LED lights won't come on at all, even if I select it on the menu. I believe they are called daytime running lights,however they don't run in the daytime. Am i Missing something?

Cheers for any help...
