Thread: D4: Suspension will raise once system cooled message

Has he left it to cool?

Only times I have seen this on mine was immediately after lots of height changes ( showing someone what it could do )

Seems too much change in a short period can bring it on... otherwise mines been fine.

When you say "happened over night", do you mean it occurred at night without multiple uses of the system to do height changes frequently (which normally triggers that message)?

If so then something is not right. Not sure how temp is detected but that would be a potential fault point.

Not sure if the OBD dongle mentioned is a LR specific product. A generic tool will not read much and almost certainly won't read the suspension ECU.

Only time I've got that message was when driving up the highway with a flat tyre. Suspension was attempting to compensate for difference in vehicle ride height.

Stopped and pumped up tyre and everything returned to normal (had to replace tyre next day though). The suspension fault message was the only way that I knew there was something wrong. The D4 continued to drive on a flat tyre with no unusual "feeling" in the vehicle at all.

I have since installed a decent TPMS ......................

Actually it could also be a leak that is causing the compressor to run for too long.

"Overnight" was a figure of speech, although it literally was fine when parked up that night and then "out of the blue" (another figure of speech) the next morning it would not adjust the suspension. So the compressor couldn't be hot (120DegC) to hit the too hot cut-off point.

The system is designed to prevent excessive running of the compressor, while I've not seen that message on a customers vehicle, I assume thats what it is.

Remove the plastic cover (or bash plate if it has one fitted) on the compressor and see if its full of mud, clean it all out if it is.

Well in true Landy fashion it self-corrected! Friend shifted it a few meters in the driveway and the suspension popped up to normal height. He the cycled it through the settings no problem. Go figure.

Worth removing the plastic cover as suggested and have a look.
Mud/sand builds up under there and may be impinging on the compressor temp sensor.
