2014 - Range Rover Sport HSE: On a few occasions when the truck has sat out in the sun on a hot day (90 degrees plus) for several hours, upon starting I get several faults, ABS, Brake, HDC and ride control among other. Power steering and Cruise control also go off line. If I drive the vehicle for 15 plus minutes upon restart most the faults will clear and then once in gear and moving the rest auto clear. This has only happened on hot days when the truck is directly in the sun for several hours parked. Additionally the code seem to back off from RED to YELLOW as I drive the vehicle, with power steering coming back on line first.
Any ideas where to start looking?
Thanks
Mark
