Hi, I Bought my 320d m sport last sunday, The car is lovely but i have a problem with 1 headlight? It is about as bright as a side light? I have changed the bulb but this didnt help. There is light but just not very much. I have no idea how bulbs work but i would make a guess that the 2 wires connected to the back kind of ignite the bulb which makes is light up? If this is right could it be that 1 of the wires has a break in it?
