I've read that it's most likely the compressor. But none of my shocks are sagging. It's always at normal height. Just curious if it could be a ride height sensor instead?

 

pull the codes.

 

I googled this alot, found a write up where they had the same warning and no sagging too. First change was teh air dryer for the compressor. I am going to test this fix on mine first as it is cheaper and also a really good idea on these older years.

 

When it says "Normal Height Available Only" will it throw a code? My LR4 does this intermittently but after the engine is cut off and I start it up again the warning lamp and message is gone. I have also noticed that after I park and turn off the vehicle my suspension will lower some on front and/or back. I am not sure if this is normal, I have only owned the vehicle 2 weeks. I have a code being thrown for the camshaft positon.

 

It should throw a code. As for the vehicle lowering after parking, it is normal for the car to let some air out after offloading some weight (the car is just adjusting back to proper height), or if the car is parked on an uneven surface (car will let some air out to level a bit). But, if you are coming out to the car kneeling front or rear in the morning, or tipped on one side or corner, this is not normal. And don’t ignore that camshaft position error, especially on a 2011 car - they are known for timing chain problems. If you bought the car used from a dealer, get it back there pronto to have it checked out. I believe most states require dealers to offer at least a month of warranty on a used car.
