Left high beam not working. Not the bulb, not the fuse
I recently purchased my 159 JTDm with bi-xenon headlights.
As you know, when you turn on the lights and then the high beam, the halogen bulbs must illuminate, as well as the xenon bulbs.
However, only the right one turns on, and I receive a message in the screen with a pretty drawing of the car indicating failure in the left parking light (that is ok, by the way).
I have checked the electrical scheme from eLearn and there is a common relay (T2) turning on both bulbs, and then a fuse for each one (F15 and F14). I have checked with a multimeter and both of them are ok, and changed the bulb twice, with no luck.
The strangest thing is that if I measure continuity from the fuses to ground, I get 0 ohm in both of them (the bulbs should show somewhat higher resistance, I think, and the one that is failing should show open-circuit).
I also cannot disconnect the circular headlight connector to check the wiring. Anyone knows how to do it?
