Weird Fault. When vehicle gets up to temperature, engine keep going in re-juiced engine power. also been connect with DSC Fault & HDC Fault, also might be connect to noise brake squeak. I know the is some fault with battery cable, as found by a Land rover dealer when I needed a new key fob done. Last serviced 7/11/2015. Any Ideas?
