Air suspension

Post by Morley » Fri Apr 10, 2015 8:54 pm

Hi guys, just bought a disco 2.
I know it's a common problem but can't seem to find a similar tale to mine anywhere.
Rear suspension is low on nsr compared to osr. It does not go further down over night and drives fine. It pumps up when put in orm and deflates as it should but returns to a lower height than the drivers side. Pretty annoying. Both ride height sensors are brand new.
Could this be that they have not been calibrated to ecu properly? Or could there be a more sinister issue? Any help or suggestions would be massively appreciated.

Thought most fixes for that was to ditch the whole lot and fit proper coil springs ....

Done that on my last disco. Thought I'd give the airbags a go. I carry a fair bit of weight in the back so the sls seemed like a good idea. I'm sure it would be if it worked properly!!

Hello Elvin,
I have lifted this from another forum.
I don't know when your sensors were changed, but this might be the answer you are looking for.
Hope it helps


Im convinced this has to be something to do with the electric side of things, as everything seems to work perfectly, other than the god damn leaning!

Hi mate, my understanding and experience leads me to say this: if you change your ride heights sensors, you will not need calibration IF you follow this 'how to':

1 Most importantly, you need to disconnect the car battery neg lead, so the slabs ECU doen't know you are fiddling with it!!!;

2. Disconnect the electrical contacts on the ride height sensors and remove them, then install the new on,es and reconnect them electrically;

3. Reconnect car battery neg lead and fire her up. Marvel at the stat of level Disco-ness.

Hi Nigel,
Have read the exact same thing on another forum. The dealership changed both sensors 2 days ago when I bought it! It's under warranty but thought maybe it's something I could do myself with a hammer! I use the vehicle every day and dont really want to have it off the road for too long. Was hoping somebody has had a similar problem in the past and could advise. Doesn't seem like an airbag, valve block, or compressor problem and the sensors are new. I'm confused as to what could be wrong.

If its under warranty (LR dealership?.) don't do anything that risks voiding it. Take it back and stand your ground.

Ok so, you can actually level air suspension with a 7mm spanner and a hammer. Awesome!

Not sure how to adjust this, your gonna get dash lights and need diagnostics if you try yourself. Maybe challenger 4x4 Nr Aldershot can square it up for you.

I'm on genuine springs and Airlift 1000s, too much to go wrong with the air bags, actuators and compressors. one leak and your stuck

Have sorted it!
Ride height sensors held in with two 7mm bolts. Took top one out and slackened off bottom one, widened top hole with a drill, rotate sensor to desired position prob 2-3mm, re tighten both bolts, 40mm of suspension gain on problem side.
Sits nice and level now! No dash lights!
