Since the fault has just appeared, i would saying a "missing" link on 4-5 would indicate a control board/wiring failure.
That is of course assuming the link or cable connector for 4-5 hasn't come out.
Phone British Gas (or go online)
Pay the £75 call out fee. Sign up for the £15 per month boiler cover.
They will fix any fault (within reason) and warranty the boiler for 12 months.
Two day wait at the moment though.
