Hi guys, got my first taste of AYC light today. Doesn't come on till about 500 yards after take off. Could this be a speed sensor? Like I say, after starting her, light goes out, but comes on again after driving about 500 yards. Checked the oil straight away, and its at the correct level and nice and clean.(changed it as soon as I bought the car) Doesn't seem to affect the drive as she still takes roundabout like she's on rails. Any ideas would be appreciated. Cheers. Oh and does anyone know of a good fault code reader that reads these ECU's? Thanks again.
