but then came back for a week it now off again and i cant find the problem fuses all look intact

if all of you gauges have gone at once i would suspect it to be a power to the dash fault or the voltage regulator on the dash its self. this is part of the dails circuit board. you may need a new/second hand set. only around £30 from a breakers.

multi timer is connected to the instrument panel lighting however unsure about function of the panel itself

I be looking at buying a 2nd hand instrument panel and dropping it in if you are unsure ow to check voltages

mfd is working
speedo - no
rev counter - no
mileage display - no
water temp - no
fuel gauge - no
dash illumination - yes
fuel light - yes
P brake - yes
engine check lights - yes

also looks like a mouse has been in the engine bay but no sign of damage to wiring

i can check the wires with a multy meter but need to know there function from a wiring diagram to make sure im testing the right ones
