No tail lights
#21
Fun times.
Until I could take a decision regarding the replacement of the BPM and the version to use, I decided to wire the output of trunk fuse #21 directly to the tail lights -- I'd have the dashboard error, but at least, lights.
Removing the tail lights assembly, I banged the left one a bit too hard, and noticed the second filament of the brake/tail bulb had broken down. Dammit. So I went to buy a spare.
Mounted it : EVERY. THING. IS. WORKING. PROPERLY. Tail lights are back on, as well as the front side markers.
I don't understand. I'm guessing the original bulb was misbehaving even though both filaments looked fine, but I can't see how it would wreck such havoc. It's not like the tail lights and side markers are mounted in series? I think.
The battery, unfortunately, seems to be on its last legs... currently in charge, it didn't have enough power to start the engine.
Not to add insult to injury, especially since I'm the insulted one, but I strongly suspect that the battery was fine until I did a short circuit a couple days ago and put the car in lockdown/antitheft protection.
All this to say: sorry for having wasted your time with a nonexistent problem

Reddevil ,
The terms fog and running may be mixed up on the print , different English languishes
But yes on power at the red and blue which should be the center pins on the bulb sockets
There is a history of the socket ground path lacking which would allow enough current to pass and illuminate the bulb but not enough to not trigger the current sensor to give you the light inop indication
incorrect bulbs will do this

Not quite sure of the wire colors you mentioned but we can go further
Do you have the 3rd brake lights or high mounted upper center lights during brake pedal depression
Fuse check
Relay swap
This is a pic for a fuel pump issue but your relays are in the pic
