I have a vectra 2003 which has started showing the brake pad wear warning light on the dash. How reliable is this sensor could it be giving a false reading? The car has done 40k

many thanks for any help

Generally reliable, but you could always confirm if the pads are worn by taking a look at the front pads through the wheels to see how much meat is left on them.
