I have a question over here 2005 Land Rover LR3 suspension fault.. There was a wire disconnected where the compressor is, so I have fixed that problem install everything back on just like it's supposed to be. Now I have another problem suspension seems like to be slow raising up it takes about two minutes to fully raised up to the highest point. What do you think would that be a compressor issue, maybe it got overheated and this cylinder ring
needs to be replaced?

 

you might do better in the LR3 section

 

Moved to LR3 section.

 

Check the air dryer on compressor.

 

There are rebuild howto videos on youtube:
Piston ring: Dryer beads:

I rebuilt the compressor using the kit and video above. It lifts when I turn her on and lowers when I shut her off. Here's the thing.

around 20-40 seconds after I turn her on, the suspension fault light comes on. I'm riding high and everything seems normal and when I turn her off, i hear it lower.

I can't lower it when it's on.

I changed the R7, F3 and FL10 60A (this one was burned prior to rebuild).

The compressor kicks in when I start and fills the bags and truck lifts, then it stops and the light comes on.

 

sounds like it could be a sensor issue now.

 

Sensor? crap. now to find which one...
