i changed it cause the car died on me, this is what happend, i park up out side a job in front off my boss van left the car unlocked. my had to go out, jumped in car and wouldn't start the AA tryed allsorts of things, i got searching the web all the things pointed to Ecu not reading the key, changed the fusebox from a car im breaking, orderd an ecu kit through DN spares. Also just tryed to do an alarm test found out the electric windows aint working, think it might be a power fault to the fuse box.
