Lost & desperate
What I've done so far to no avail?
- taken off the the battery & light switch control unit that looks neat, clean & as good as possible. Put it back. - taken off the bumper. - taken off the light blocks on each side. - swapped the dipped beam bulbs just to be sure. - all the wires looks clean, neat & as good as possible. No cut wire, no bare part, no corrosion & no moisture at all anywhere! (I can post a picture a bit later). What's the result? Nothing! Bulbs look good since the left one is now on the right side, and again lighting on that right side when the left one (with the right bulb) looks desperately dark! So far I haven't switched off the battery and didn't tested the inside fuses. The 10 engine bay fuses looks as good as possible. What could be my next move now? Where could be hidden the nasty culprit? Please...

In the engine compartment fusebox you have 10 fuses and 12 fuselinks. Seems to me that you did not check fuselinks #9 and #11 I mentioned.

Some pictures, first the engine fuse box (@Roverlike all fuses looking as good as possible included #FL9 and #FL11) then 2 pictures of my left light block connector and wires.
I must precise that the inside of both light blocks look neat & clean as well. What could be wrong so far? I'm gutted & cross: all is lying on the ground, I fell totally useless without any valuable clue!

The LSM connector for the LH dipped beam is CO937-7 and is a mauve coloured cable. Try unplugging it and checking for continuity and a short to ground.

Have you removed and inspected the light control module? Once you've taken it out and disconnected the multiplug, prise off the black slotted cover and look for corrosion on the circuit board.

I've removed it and examined it closely. I've already told it is neat, clean & without any damage. All that I can see of the printed circuit is shiny & tidy. Connectors are fine. No corrosion at all neither inside nor in the engine bay or anywhere else, from what can be obviously seen. She spent her 13 first years of ownership in one of the sunniest & driest area in France, near Perpignan, close to the Spanish borders. Since then she didn't move very far North.

I can't find anything with "CO937-7": would you provide me with a link or picture? I've had a close look inside each light block L & R: all is fine, every brass (or copper) bit looks shiny & without the slightest hint of corrosion. But I cannot test anything in those plugs: my multimeter cannot show any voltage even when I turn the light button inside and test the good right side. I should have add that the main beam is fully working on every side left & right.

The LSM is the light switch module. If you unplug the connection on the top that is CO937. Wire number 7 on that plug is mauve, and that is the one you should check for continuity and a short to earth.
