ok so the model should only have 1 rear fog light that will come on , not both. is your car right hand drive or left hand drive? the light that will work will be on the same side as the drive side, also have you confirmed that there is a wire going to the fog light bulb itself?

ok, thanks, ***** ***** trying to pull up a wiring diagram to see what we can test, does the fog light switch have a light on it that comes on to indicate that the rear fog light is on? are there issues with any other bulbs?

Customer: replied 1 year ago.
the indicator light on the dashboard is on
Customer: replied 1 year ago.
no problem other lights..all bulbs are working
Expert:  Lou P replied 1 year ago.

ok, so we know the switch is working, so has the rear fog light ever worked? there was an issue where the fog light wiring was left disconnected at the control unit for some years that i have found.

Customer: replied 1 year ago.
I am not sure...I did annual inspections and i have been told that the rear fog lights do not work
Customer: replied 1 year ago.
they have to be fixed before approve the EU inspection

Expert:  Lou P replied 1 year ago.

ok, so there are 2 wires at the fog light, a black wire (ground or earth) and a mauve wire or violet not sure what color mauve is lol, and it changes to a orange wire. the wire gets power from fuse 25 in the interior fuse box, can you confirm the colors to make sure i have the correct diagram?

Customer: replied 1 year ago.
black and violet
Expert:  Lou P replied 1 year ago.

ok so far so good, does the black have connection to ground?

Customer: replied 1 year ago.

Expert:  Lou P replied 1 year ago.

No i did not

Customer: replied 1 year ago.

Expert:  Lou P replied 1 year ago.

ok so now we check for power at the wire with the switch set to the ON position

Customer: replied 1 year ago.
okay
Customer: replied 1 year ago.
the violet has no power
Expert:  Lou P replied 1 year ago.

ok so we need to trace that one, did you confirm that fuse 25 is the fog light fuse?

Customer: replied 1 year ago.
actualy number 10 is the fog rear..and I checked that okay
Expert:  Lou P replied 1 year ago.

ok so my diagram is close but not 100%, so there is a front control module that controls the lights from what i can find, but i cannot find where the module is exactly at that is the issue i am having. we need to test for continuity from the violet wire up to the control unit.
