hi, i have a 2.0l 8v cupra n the abs light goes on n off intermitantly, i know there are two sensors at the front n im guessing it could just be a loose connection. However earlier on (whilst the abs light was off) i was braking in this lovely english weather and it felt like the abs kicked in, but then the pedal whent hard as if i had pumped it with the engine off, then the abs light came on n the pedal relased itself, this happened simultaneously. Any other reasons apart from a loose connection for the abs light coming on? ?!
