Turns out the two left USB ports have corrosion in them. I did argue that it's likely left over from the previous work as the Mac hasn't had any water near it since, but they don't agree. £30 to replace them both rather than paying for the £75 AC+ excess so not too bad I guess. I've been using my work 16" since and it makes me glad I have the 14" for personal use, the 16" is such a behemoth in comparison.
AC+ expires in June I think, do Apple send out extension emails when that time approaches?
