I tried turning the wheel want reset the dash says suspension inactive also 35 mph
Unfortunately there could be several reasons for the failure, including a defective air spring, loose or broken connecting tube, but more likely the pump or the ECU. This is NOT a job to tackle yourself unless you have the experience. You need to get the vehicle to a specialist Land Rover shop (NOT a dealer) and have the system checked by someone familiar with these problems

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

Airbag resets need to be taken to the dealer or someone with access to the right diagnostic equipment(unlikely) Store bought code readers will not work.

Humming sound is from the front plastic cowling on the outside of the car, at bottom of windshield, This plastic cover warps over time causing the sound. A little silicone adhesive to tack trim down will alleviate the noise.
2. Air suspension inactive light can illuminate for multiple reasons, To avoid unecessary expense the car should be scanned with a land rover scanner (dealer or aftermarket (expensive) unit)). The compressors do go out, Compressor is the domed shape unit under the spare tire.
