    2018 Discovery Si6 HSE Lux Santorini Black

    Rear fog lights.

    Both rear fogs have decided to stop working. Tried over the weekend as was quite foggy.
    Not checked the fuse yet, but the orange symbol comes on when i turn the stalk. Front fogs are working fine.
    I had the small trailer attached, and the indicators, brakes and sidelights were working fine.
    Disconncted the trailer lights, incase they were interfering with the cars electrics, but still no luck.
    I will check the big trailer, as it has in built fogs, later on in the week, when i have time.
    Any ideas apart from the fuse?
    The left lamp cluster was replaced about 6 weeks ago, so am thinking maybe they had to disconnect the fogs and forgot to plug them back in, as maybe they are on the same circuit?
    Were working before the car went in. Any helps appreciated, thanks.

    (I had similar problem when i picked the car from new just over 3 years ago. None of the sensors were working, neither front or rear, or side ones.
    Car was fitted with a fixed towbar, and as i had thought, all the reverse and front sensors were running off the same wiring loom and the garage had forgot to reconnect the plug afterwards, when putting the bumper back on).

    The fog lights are deactivated when a trailer is attached (so that you don't just dazzle yourself with the red glow on the front of your trailer). Check the electrical socket is clean and that there isn't a short simulating a trailer being attached.

    JonM the socket is clean, plus am using a 13 pin to 7 Pin adaptor. Also squirted Wd40 in the socket, plus it has a rubber protective cap over the towball and socket to keep dirt and grime out. I always take the caps off, when washing the car and give the sockets a quick blast with the hose pipe, to get rid of any dust and salt etc.

    If that's the case that they disconnect on attaching a caravan, or a trailer, does that mean just the fog lamps on the caravan or trailer only function, as car ones are deactivated?

    Am pretty sure on my big trailer with integrated fog lights, the rear fogs on the car are on as well, unless the feature your describing is for MY19 onwards ?
