It says the Code is for a fuel additive. This does not sound like something for a normal Ford Focus. The Code could be wrong as submitted, or there are some Blu-tec style cars with diesels using a Urea additive that needs replenishing when low.
2011. Why does pressing AUX button connect to FM radio?
It is broken and it is not a simple fix. The simpleist you can get is pulling the fuse to it for 24 hours in the hope it might reset.
Unless someone has connected an FM Radio aftermarket to the Auxilliary Input lead.
Or if it is Bluetooth enabled and you have a phone, is it playing your phone playlist? That happens to me.
