So, if you're having an issue with a car faulting, telling you there is a trailer when there is not? Then you need to look at the trailer brake lamp circuit on your towing electrics sir

Thanks Cam-Tech-Craig.
In my case, I can add a dummy load to the LED circuit, increasing the current drawn, and hopefully trick the sensors.

Exactly what I would do sir...

Sorry fellas to revive an old post. I just picked up a 2008 Vogue SE, Has a towbar fitted. I don't intend on using it. But everytime I start her up I get the "check trailer light", The trailer icon also stays on also and will remain on until I turn my sidelights or main beams on. If i were to indicate without doing this the indicator blinks rapidly as if when a bulb is gone. Am I able to just remove the fuse for the trailer lighting or how best can I resolve, Thanks in advance

Got to the boot and unplug the module should be that simple - you may have an aftermarket module like me causing mayhem. I got a used look and module for not much and wired it in all good now.

If you have genuine the modules go for less than £20 on eBay so maybe worth trying one before completely giving up Current stable:
