This link takes you to a site which has the trailer box fusing details, and checking the fuse may be a good place to start. I haven't as yet discovered where the actual box is but I'm still looking!! https://fuse-box.info/peugeot/peugeot-3 ... 2016-fuses

This video shows you how to confirm the trailer unit is configured.

In the UK you get a 3 year warranty on cars, if this applies in your country then you should be able to get your dealer to fix this.

On my C5 X7 Tourer the towing (which I presume is the same as trailer) ECU is hidden behind the trim panel between the rear wheel arch and tailgate. I further presume that any relay would be part of that.

If the relay is working and you switch the hazards lights on you might be able to hear it clicking and help locate it.
