is an abs light on a fail then? as abs isnt compulsary, its just another safety device. with the light on it just acts like it has normal 'old skool' brakes. & also as for the spare wheel, in the last 4 years ive never seen the mot tester go in the boot let alone check the spare, just the 4 on the axles. (he'd have a job getting to spare anyway as sub is in way hahaha
