Anyone know, how the valve works for letting out air on the compressor unit?

Just that mine has just decided to stay in the 'open' position, therefore pumping air out of the air intake pipe instead of into the air shockers.

Thanks

Self Leveling Suspension (SLS) <--- do a search on these, you will find some stuff you need, recently someone on here did a service on theres, after ford said you cant, might just help you, drop them a PM if you need.

I have a friend who has SLS but had too many problems with it, so he took it off and replaced them with standard shocks.

i intend to dellboy999

i found pretty much what i already knew on those previous posts thanks anyway. i've replaced the compessor and shocks already a number of months ago. stopped leaking and such. but this problem baffles me, there is constant power running to the valve i've tested this. so it must either hold open the valve or hold it closed (guessing switching polarity cylces this state). at the moment it must be holding it open.

I will take up the idea on those posts though of connecting a seperate valve to the air lines to instantly lower the back :) (when i fix this problem) have to connect a switch through the circuit breaker to disable the pump too.

Thanks, Paul

There is a switch located just above the diff. It may be out of adjustment.

Check a) Link at diff not disconnected or wiring harness plug at diff not loose, disconnected or dirty. Have you tried the self diagnostic test; if so what codes? There is an internal diode in the vent valve solenoid that fails if earth and positive wires are switched so has this happened? But do the self test first; no tools are needed.

ive got SLS on my XE, but i havent touched them since i got the car, so i dont know if they work proply or not.

Blue - yes thats excactly what i want to know thanks... i'll do the self test tonight and check underneath the beast tomorrow morning. If it is this diode in the solenoid (dont know if wires were switched) it'll be another compressor unit :( unless there is a way to fix?????

Thanks again to all.

Buy a new diode 50 cents worth.
