Had bother wi mine these last couple o days too after a battery disconection (52 Leon). Drove me up the wall Listened to the advice of my local sdealer and got led RIGHT up the garden path. Took advice off here and Bingo sounds again. Turn the engine off and tak oot your keys turn on the radio and leave your car, dont forget to lock up. After 55 mins (just under the hour, and be precise, or you'll miss it) go back open up and wait for a couple o minutes THEN watch in marvel as the 2000 appears. Enter your code and hit the Prog. button and you'll be laughing sandbags.
