Hi everyone. I have a 2001 Disco with SLS. The fault light does not come on, but the vehicle won't lift. If I try and put it in ORM, the light just flashes and never shuts off; the vehicle doesn't rise at all. Any thoughts?
The compressor is located on the N/S chassis rail in a plastic box.
They can be changed in probably less than 10 mins, when you buy the new one it comes as a complete unit, control valves and box ect.
I have changed two this week.
Make sure the pipes are free from water. The air intake is located behind the N/S rear lamp cluster (body not bumper) and if the top to the filter is not on properly can fill up with water from the sunroof drain tube.

OTOH, maybe not. Mine went into tail-down mode when it was put on a 2-post lift to change the tyres and no amount of button pressing had any effect, not did any warning lights come on. A quick reset of the ECU under warranty cured it. For the OP's sake, I hope it's that simple for him.
(Why a vehicle designed for off-road use throws a major wobble when all four height sensors go temporarily out of range at once is a question I have not been able to answer.)
Thanks for the responses. I can tell you that the compressor does fire up and it pushes air into the bladders. I took off a tyre and set the frame on a jack stand and lowerd the axle. I heard air coming out as I lowered it. When I put it back together, it was ALL the way down. Started the vehicle and it pumped up the rear about an inch before it shut off.
Make sure that things like all doors (already mentioned) are closed, there might be another gotcha. Pretty sure it's not low box, that is requirement for the HDC to become active though.
Define "forever". My 2001 DII takes around 20s to rise from normal to "off road" height (that's a 2" lift back end only ISTR). Slow enough such that you can barely detect the movement but it is moving. It doesn't zip up and down like a DIII does.
I could bleat on about 7 seaters not being type approved for steel springs etc. But it is just that the SLS system is very good at it's job especially if you do heavy towing.
