Hey, so this is my first post on here and I've only had the ol' gal for about 6 months so I'm still getting used to all the technical terms/acronyms and whatnot. Anyway, the rear suspension will drop all the way down overnight about 3 out of 10 nights and it's slowly getting worse. About a month ago it was only once every ten or so nights. I've looked around and I keep hearing that it's probably a leak in the bag(s) but the weird thing is that it will never do it while driving (even with 7 people in the car) and it always drops/raises 100% evenly.

I was thinking maybe an issue with one of the sensors? I'm going to get under there and try the spray bottle with soap/water trick later this week when I have time but was just trying to get some info in the mean time. Also, if the bags aren't leaking I pretty much have to fork over the cash and take her to get scanned right? Anything helps, thanks in advance!

P.S.

I love the air suspension so there's no need for the coil kit suggestions.

How many miles on the truck, have the bags ever been changed and do you have any warning lights on the dash?
Usually when both sides drop equally it is an electrical issues in the computer, not a height sensor. The air bags are not tied together, so one side can not pull the other side down.
You will most likely need to find a shop that has a computer with Rover SLS software in it so the codes can b e read.

That's what I was afraid of, she has a little over 115,000 mi on her right now. I took her to a LR mechanic here in town when I bought her and had them do a full inspection, they didn't mention anything abi

Sorry accidentally hit send. But they didn't mention anything about the bags/suspension even though it was doing that at the time, and there are no lights coming on the dash.

So, find a shop with the correct computer and software, other wise you are wasting your time.

Put the air bags in extended height mode and leave it overnight See if it still drops. The bags usually leak at the fold and when you are in extended mode there is no fold and they usually don't leak.

Here is a guide to the SLS system:

Great advice acamato, that guide is amazing! I'm going to try that tonight. But I think mike is right and I'm going to have to take her in to get scanned.

Thanks for the help guys, I may come back for some more advice when I find out what's actually wrong with the system.
