Just a thought, firstly welcome, hope you enjoy your new car.
Secondly, there is a rear fog light flasher unit that some fit to these cars, allows users to alternate between using the rear fog as a normal fog light, or having it as a rear flasher, when in track use, like formula one cars have in the rain.
Search flea bay for RS MK3 fog light flasher and you’ll see what I mean.
Could be that the previous owner has fitted one.
