hi guy the temperature light keeps flashing on my mk2 dash i have changed the clocks to see if that was the problem but it still flashes away the rad has been changed and it had a service a few months ago and past its M.O.T it goes off form time to time but will flash whether the car is hot or cold is it something to do with the coolant reservoir wiring?
Either your water is too low, you're overheating or the wiring to the header tank is broken somewhere/header sender is on the blink.
