Hi, this is my first time on the forum. Ive had my 2006 X5 for a month now and i'm very pleased with it. Two things i would like help with are: I sometimes get a warning sound (3 bleeps) when driving out on the open road, but nothing shows up on the display, its not the speed warning sound because its set at 70 mph, this sounder appears at different speeds. The on board computer shows around 41 mpg which i would think is too good to be true. Are they accurate? I will try and record the mileage the next time i fill up and calculate it manually. Thanks, Stevie.
