self leveling suspension
 

Hey guys i have a 05 4.4 with the rear air suspension. I have had eibach springs put in the front and the dealership lower the rear for over 2 years now. Just today i get in the car and notice self leveling suspen inactive. This has popped up before but just goes away and i turned the car off and back on and it went away again. My concern is that my car warranty is up in 1000 miles and was interested if anyone has had this happen or heard of this before. I have an appointment tomorrow just wanted to go in with some knowledge before if possible. Thanks

ok did some more searching and found some info about it. Seems like nobody knows the exact reason the error comes up or 100% way to get rid of it.

Been there done that...in a nutshell my dealer changed pretty much every part related to the self leveling suspension under warranty. Good luck :thumbup:

I had the same message...and there are several faults with it...

What I did...is take out most things out of the trunk...and exposed the suspension...I could hear the air bag inflate every time i started the car and alos numerous times while driving...I ended up replacing a seal that was damaged...no more message and car looks to be level...

the thing is that there are soo many different things that can cause the inactive message, from a simple intermittent relay, to a sticking air valve, a bad reading from a level sensor, etc. Good thing for warranty, let them read the fault memory to see what caused it... then they'll take it from there. It usually involves checking the electrical part of it for problems as well as the mechanical aspect of it. One piece of advise would be to get them to check the system for leaks, especially the bags. They have a habit of developing slow leaks over the years. Spray them with soap water and they usually have a solid ring show where the bottom of the bag folds onto itself. If the bags are leaking, let them get changed under warranty, only pays 2.2 hours labor for both of them.

after putting on the front springs... doesnt the rear lower by itself or do you have to go to the dealer to lower the rear?

there is a kit available now that uses links to modify the rear suspension geometry and lower it safely. Saw it in another thread, but forgot who makes it...

for 2002 air suspension I would simply need the lower springs correct? withoout this kit you were mentioning?

It looks like BAV Auto makes the lowering kit that keeps the original air springs. Here's the thread that talked about it...
