Good morning everyone… I know I have touched on this before but I still don’t seem to have any real pointers. I am still confused by the way the external lighting works on my W220 Sclass, it something that I have not been able to answer so far. Basically the headlamps work when the keys are not in the ignition. So what I mean is that I can unlock the car and turn the full dipped headlamps on with the light switch dial without even putting the key in. I find this very odd, and it causes a specific problem when the headlights are set to the Automatic mode of operation, as the Xenon's fire as soon as the key is turned to the radio position (ie. position 0). I spend quite a bit time in the car stationary with the engine off and radio or TV on and having my Xenon's going has meant that I can no longer use the automatic headlamp feature which is a shame as its useful. So I guess this raises 2 questions. 1 When set to manual should the headlamps operate when the key is not in and the engine not running? I would have expected the running lights to work but dipped headlamps to only work when the engine is running. 2 When in automatic should all the exterior lights (ie. sidelights, license plate and dipped headlamps) come on when the key is at position 0 or 1 but the engine off? It’s a 2000 S320 LWB, W220 model.
