You could have the height sensor out of whack. Does it move up and at the front or rear. Like it's dancing?
Nothing is dancing or was dancing... it acts exactly the way it did before the compressor failure.
In my eyes, EAS behaves perfectly. No dancing, no sagging, no weird states after power off.
Also, achieves any ride height immediately within seconds.
I had EAS issues before once on another P38a in the US.... so I have seen all the weird behaviors...
When I got this one 6 months ago, EAS was perfect and it has been flawless until 2 weeks ago when the compressor failed.
Now the compressor in there was rebuilt... it says that on some painters tape...
But was it because a failure of another EAS component???
... at the moment the only possible failure I can even imagine would a leak/problem in the air feeding to the storage tank.
Assuming the circuit is compressor -> tank -> EAS ports -> air bags
As the vehicle holds height for weeks, rises to any height immediately, no errors or issues.
Hoping it was just a bum compressor.... the truck has 200k miles... visual inspection of airbags so far shows no cracks.... the fact that the car doesn't sag on any corner would indicate to me that there are no leaks in airlines or bags....
Just felt the compressor was running quite a bit once installed... but then again I have no idea how much it should run....
and the whole system was empty.... so lots of air to refill....
