Good news guys! I got my mini back from the garage this week. The lovely dealer principal has said they will replace the dash, but best of all they seem to have improved the fuel economy as it is now doing on average 44mpg. Don't know what they did to it but I am a much happier bunny! The rattle in the dash is still there but seems to be common as the parts are out of stock to put it right! Fingers crossed
