UPDATE
Well the washer jets problem is now fixed. As I had read on here the filter was blocked so removed the entire bottle and cleaned it out.
However, now the offside headlight washer jet is not spraying water. I've read on here it's probably from air in the system after emptying the tank and if I keep using it, it should come back on again soon.
However, still no light even with no water in the tank so mine obviously doesn't have it I have almost every option box ticked too. Must be that some have and some don't.
