I have a 2005 range rover sport. Recently a message on the dashboard has come up saying that the suspension will operate at normal height only. There is a orange light on also which shows a picture of the car with an arrows to either side of the top of the car implying that there may be some toppling over issues? The lever which would normally raises or lowers the car does not operate and no longer lights up.

I have just had a New compressor fitted from a Land rover specialist as this is what happened before and was told it was the compressor.

Any ideas what it could be?

A rusty/corroded air reservoir. If it is leaking, the compressor can't build the pressure up to the required 18bar, bringing the light on

Spray the tank with soapy water when the compressor is running

hope the software update and new relay had been fitted as well alongside new compressor

having fault codes read would not do harm as well

Going in tomorrow to get plugged in. Will update as what it is.
