I have a 2017 First Edition with air suspension. I have lately seen that the front shockers sag overnight. It is almost to bump stops, rear stays fine.
I have lifted the normal height by 1.5 inches with GAP tool.
I removed air suspension fuses to check if the self leveling sensors make both sides sag the same and if there is a leak on one side only. Both sagged the same amount still.
Any one noticed this? any pointers - bad sensor? module?
Thanks

 

Not sure if these work the same but on the LR3s + 4s if they sag together in the front or rear it's usually a valve block. So I'd look into that maybe, how many miles do you have?

 

I am at 65k miles

 

Having this occur at 149K miles. Following for any updates. Mine only happens when temperatures hover around 32 degrees or less overnight.

 

Rubber age regardless the mileage, so this can be age-related.
This company makes very impressive video clips on youtube, so I saved them. They seem to be in China, but advertise in US, but never had a need to check it.
With the prices some of those air suspension shocks cost, even shipping to China will be small quote in total.
