was told there was only one sensor (on passenger front wheel), its been cable tied to hold it in place, i thought that must be the cause of it, so cut off the sensor end and joined the 2 wires together temporary, but it still comes on every now and again, and stays on till you restart the car?
fluid is about centre between the max and min marks in the resevoir, could it be that? if so how do i find out which brake fluid it takes?

its a 2003 1.8 sri
