Hello everyone! Long time Rover owner here. Had membership years ago and lost account info. I’ve owned Range Rovers since 1999 and one of my current models (2011 HSE) is experiencing some strange issues. The right front air bag releases air for no reason causing the entire vehicle to rear on bump stops. I jacked it up, assuming it was a leaking bag, but no luck. Amazing, when I put the vehicle back down, it raised right up and drove fine for a month. Last week, I heard a hissing noise once again coming from the right front feel and, lo and behold, the front dropped followed by the rear. Jacked it up again, started the engine, and the airbags filled up and it drove fine until today. I know it’s not the air bag because it holds air for weeks on end when sitting (I don’t drive this one much) until something happens that makes it release air quickly. My only thought is height sensor is bad. Anyone have ideas?
