I know that the air suspension will occasionally add air to the system when adjusting for load, etc. However, it seems to me that this started happening to my Defender a bit more often than it should. I would say when driving around once every day or two I'll hear it add a little air, usually when just driving around on the road. What's everyone else's experience this sort of thing? I wonder if perhaps I have a slight leak somewhere?

 

It is normal behavior.
If suspension is dropping when parked then it's a problem.

 

How old is your Defender and how many miles do you have on it? You may have a slight air leak, and as stated by TeddyG, if your vehicle drops after being parked for 24 hours on any side, you definitely have a leak and you better address it asap before your burn out your air compressor.

 

That's an OCD defender.

 

Is this still true if I park at access height? Is it easy to see?

 

About 2 years and 18K miles.

 

yes, it will be asymmetrical drop.

 

So I no longer own my 2023 Defender 90, just popped in to see whats happening here with the gang and had to reply to this mysterious air suspension dropping phenomenon.

Most times when I got in my 90 after an overnight park the front suspension would lift up almost 1/2', and the rear suspension after just about every stop sign or red light stop would raise up a little bit. I took it to three different dealers, LR Fort Myers Fl, LR Naples Fl and Hendrick Land Rover in Charlotte. All three kept the car overnight and experienced the suspension raising on start up and said I had zero leaks, no faults and everything was good. My 2022 D90 also did the same thing.
