Hi fellas.
I am having the HDC air suspension inactive message with my 05 land rover range rover l322. The first time it happened I hook it up to my allcoms reading tool and it said steering angle sensor, a week later my allcoms tool stop communicating with my car computer nor does the maxidas of my buddy. The issue started and stayed on and off for 2 weeks then went away for 3 weeks till I washed I front end of the engine then decided to come back. I can see the steering wheel angle sensor movement through the 4x4 option on the screen, when the lights come on it will freeze for sometime and then start working properly while the lights are still after turning the engine off and on the lights go away. Now I realized the lights won't come on when the sun is up meaning the head lights are off but will come on in night and non sunny days when the head lights come on automatically. So no issues when the head lights are off.
New battery, alternator, radiator, water pump, thermostat assy,all cooling hoses replaced coolant tank reservoir as well.
Does anyone experience anything like this b4 please help
