Hello I am new Owner of a Range Rover sport it is a 2008 tdv8 covered about 115k I have owned the car for 2 months now and never really done much long distance driving i only use the car for pottering around town the car is great with no faults or malfunctions but after about 10 miles of driving I have a few messages that pop up on the dash that say car leans when cornering, hdc system fault special programmes unavailable, suspension lowered. Turn the car on and off and all is happy again for another 10 miles but it only does it after continuasly driving has anyone else experienced this? And what could be causing this fault. I have been reading on the Internet and I can only find battery and break lights/light switch could this apply to my fault codes? It has been in the garage but they can't seem to put there finger on it any help would be great

Thanks mat
