2007 LR3.

When I leave it parked for a while, the front end suspension (especially the left front) eventually lowers itself. I can use my GAP tool, go to Height Control, and raise it back up where it’s supposed to be. It’s fine while it’s running and I’m driving it.

What’s the issue?

 

Why do you need to use the GAP Tool for that? Will it not raise and level itself upon startup? What if you select a different suspension height? Will it level off with the other 3 corners?

If not, try unplugging the battery and letting it sit overnight. See if it sags in the corner with no power to the EAS. If so it's a leak either at some hose/connection at the shock or there could be a rupture in the airbag itself.

 

I don’t think it was leveling itself when I cranked it and ran it. I checked it before, but I’ll check it again as soon as I can. Tried running through the 3 different heights and that didn’t correct it, either. That’s why I went to the GAP tool.

 

@houm_wa raise back up by itself after I started it up. Just had to give it a sec.

 

You got a leak. Raise up to normal height, measure each corner and either pull main EAS fuse or disconnect battery. Leave overnight and measure again. If its one corner its a bag, if its both fronts its a valve block.

 

Before I shut it down, I measured from the ground to the center of the top of the wheel well trim. Left side measured 34 5/8”, right side measured 34 1/4”.

Shut it down and disconnected the battery. Next morning I made the same measurements.

Left side was at 32”.

Right side was at 33”.

So I need to replace the valve block? This part? https://www.roverparts.com/Parts/RVH...SABEgLK5_D_BwE

 

You should really do the test after you shut it off not when running. The vehicle tends to level right after being parked, usually you can hear a short exhaust noise after getting out. It will also level for a couple hours on its own when parked. Then at hour six it will perform another leveling.

 

Where were you yesterday?

 

Shut it down, waited for the normal short exhaust noise it always makes, waited a minute longer, and measured it. Measured the same as it did last night while it was running. Left side measured 34 5/8”, right side measured 34 1/4”.

If all of this is normal, should I be worried about the left front lowering more than the right front, while resting? Only started doing that recently, and it raises itself up to the correct level while running.

 

If the battery was disconnected, should it have adjusted/lowered itself at all?
