Hi,

Had this fault with my 07 RR Sport for a couple of years now and the dealer cant seem to fix it. At 70mph and oddly only in the summer when the outside air temp is above 10 degrees C, I get a number of faults, namely suspension, parking brake, HDC, transmission (get an F and cant change gear) and special programmes. If I restart it is fine until I reach 70mph again.

Does anybody have a definitive answer on this? As you can imagine, it has been rather frustrating.

Thanks,
Simon

Definitive no... but I would start with electrical and grounds. The only thing that I can think of that happens at 70 is the speed sensor will tell the computer to lower the rover to highway speed mode. If I recall correctly.
