Rear Fog Lamp Failure

Hello all, I hope you can help. 

I’ve had my car tested today (new rules I believe) and it has failed on a couple of things, which don’t seem that major and will get sorted. 

Unfortunately one is more of an issue. It’s a Nissan note, and it seems this issue, or software bug effects a few Nissan models.  The rear for lamp is always on and will not switch off. Before I bought the car it seems a previous owner removed the lamp so I never knew it was an issue. I’ve been told Nissan need to replace the ecu and reprogram keys etc. to fix this.

The car isn’t worth much - could I rewire the rear fog lamp, pop a switch into the dashboard and should that pass? I’ve read about needing a tell-tale - would a correctly labled switch with a LED marker not suffice?

Thanks in adavance.
