Air suspension help needed asap issues

Today my range rover decided to throw up a fault code for c1a20 compressor peformance not enough despite having a brand new compressor 2 months ago

First I decided with my hawke eye to deflate all the air in the system see if that would clear up any faults. It did not.

The car is now sat on its bump stops and I have just installed another new compressor hoping this would fix the fault but no nothing.

The compressor runs on start up for around 30 seconds then throws up Suspension error

I have received the from valve block to see if it was stuck or worn but it all seems great. Also removed the gallery valve block by the compressor but that seems fine also.

The one line coming from the compressor to the gallery block seems to constantly have a good amount off pressure in it is this normal ?

I'm a bit lost here as I can't hear any air leaks and all the sensors appear to be working on the hawke eye as far as I can see


Any help is much appreciated

Or last resort does anyone know a good land rover specialist in the south wales area

Thanks kris

Check the inlet air line and filter for blockages seems to be a starter.

That will be the first thing I do tomorrow I think . is there anyway of disconnecting the intake at the compressor and run it to see if it is the filter or intake lines.

I hoping I find somthing

Thanks again mate
