2004 Range rover front right suspension air leak

So many problems at the same time indicates that a negative main plug is disconnected from the chassis

Sorry computer controlled and it needs the dealer software to find the fault ,lot of money i would imagine to repair in the dealers

Call tire and muffler shop (or any shop that replaces suspensions work) it's probably a reset somewhere.

Get a kit to replace air suspension...most likely you have compressor problem like many rovers...

make sure the switch is on. it should be in the trunk area. if thats not the problem, there is probably a leak in that shock. they are known for this problem after about 5 years.

replace the air suspension bags they are leaking,.

the system should raise the truck within a few minutes, if it doesn't u most likely have leaking air suspension bag(s)

I expect this has an air system within the suspension allowing you to vary the ride and its height. If the suspension is dropping overnight this would be from a leak within the system or a valve that is allowing air to bleed back and leak out. You'll have to locate the leak which may be in one of the shocks/air bags. Being these are tied together by a common system if one were to leak the pressure in the system will equalize causing the entire system to lower its pressure. I hope this may have assisted,

If you have the coil spring suspension, then your spring for that corner has really sagged[doubtful] I suspect you actually have the rear air suspension ,and the air spring for the Right/Rear has lost air, allowing the rear end to lower down greatly. Usually, you need a new air spring when one develops a leak. You may or may not be able to see the leak with a spray solution of soapy water after the spring is removed for inspection. Sometimes you have to apply about 20psi of air pressure into the spring to inflate it a bit, then put the spring under water in a big enough tank/tub of water to catch the leak that way.

Air Suspension Inactive usually means there is a problem with the Air Suspension. However, it will also come up when alternator or battery voltage is low, or when you reset (disconnect and then connect) the battery. To reset it manually: while in P(ark), turn steering wheel all the way left, hold few seconds, and then all the way right, hold few seconds. All the warning lights will go out. Most common failure is the passenger front air strut, since batteries are prone to leaking acid, it leaks right on top of the rubber airbag and burns through it. Dealer willcharge you one hour to diagnose, or you can easily diagnose this by looking at the ride height of each particular corner of the truck. If its sits low, or emits hissing sound when you park the truck, its leaking. If you keep driving with leaky air strut, you risk burning up the air compressor, as its working extra hard to compensate for the leak. Replacing the strut is easy 45min job even for a novice mechanic, and you can do it yourself. Strut can be found new for approx $750 online. If you are fed up with air suspension issues, there is a $700 kit that converts the truck to springs, and disables all of the air suspension. Look up Arnott Industires
