Air Suspension

Hi
We have a d4. Currently off the road due to a suspension issue.
Several codes have been read, have purchased another compressor from a breakers yard but when I’ve taken the cover off the one already on the car it looks new. I have changed the relay and the 60amp fusible link after doing a bit of Googling and reading that this is what others have done. The compressor isn’t kicking in at all and it has dumped all the air out of the system. The dash says only normal ride height available. Could there be anything else before I end up taking off what looks like a new compressor for one that looks older and corroded? Is there a way to reset the air suspension? Didn’t have any issues with the suspension prior to this?
Thanks guys

Welcome.

You would do better to ask in the disco section Land Rover Discovery | LandyZone - Land Rover Forum
When you ask in there post what codes you got too.

Hi and welcome
Need to know what the codes are

Your pump mite look brand new but that don't mean it is and if its an ebay chinease special then replace it.
Remove it and test it test the sh 1 you bought start eliminating possible cause.

To be honest on the d3/4 almost anything can cause your current issue......need codes read
