I have a 06 Range Rover hse. I had my front passenger airbag go. Before that I had no issues with my suspension. I replaced the whole strut. After about a week both fronts dropped to the stops. I replaced the front valve block. Now only the strut I replaced is down on its stop. I can’t seem to find any leaks. I am going to order another valve block and was wondering what was the best way to check the airbag? It’s new but maybe it’s leaking. At full raise I can’t see anything other than the bottom of the bag. Is there any other place I should be looking for leaks? 2006 Range Rover HSE

I would check the airline connection on the replaced strut after determining that the top nut is properly tight.

Forgot about that part. When I first replaced the strut I didn’t tighten up that bolt enough. I went back in and a tightened it up and it held air until the valve block went. I did spray soapy water on the top bolt. 2006 Range Rover HSE

so i found some issues. the front valve block i brought had a crack in the body. i replaced that. i replaced both front height sensors because the rubber on the joint of the longer arm was very floppy. i drove the truck around and watched my 4x4 screen. the front passenger side is more stable and I'm not getting the drops i was seeing before. but within a hour when i park the front passenger is back down to the bump stops. i have checked with soapy water the hose that goes to the bag its good. i check the new valve body no leaks. i checked the big nut on top no leaks. any ideas 2006 Range Rover HSE

Ok so here’s where I’m at. My front passenger wheel drops down to almost the stops within a hour. Even with the door open. With the truck on it with keep the wheel up and I don’t get any hard codes. The strut is new I have done the soapy water test. I replaced the front valve body I traced the air line back to the tank with soapy water. I checked the rear vale body for leaks. Is there another valve body I could be missing? My thought is that the strut is bad but I cannot find the leak. The speed in which it drops says that the leak should be big but I can’t see it. And why can the compressor keep it inflated? 2006 Range Rover HSE
