Hello, please can anyone help me. I've still got the problem of not selecting 'low range' on my 57plate Sorento. The low range light flashes but doesn't go permanently on and select low unless the motor is cold. The problem only appears to happen once I've had a drive round the block and it's up to temp, when's it cold it works perfectly. I have tried the connectors under the car, the plugs into the ECU the dash switch, changed the oil with the correct oil. I am now thinking I should try another ECU I don't want to waste money so going for a second hand one would be the best option, problem is finding one with all numbers on the sticker the same.
