Air Suspension Issues

I've also posted this on the P38 Coil Spring thread.


I'm on the verge of removing the EAS of my P38.

I recently got the EAS fault message on my display last time this occurred was about 4 years ago it turned out to be the compressor so replaced it after the garage told me it was the valve block first (and sold me asecond hand one). So this time thinking it was the same I bought a compressor and mey mate changed it over. When you start the car the compressor fires for about 1 sec then nothing he changed over the valve block same thing after some playing about he now has the compressor running ok but nothing happens and turns out the the compressor in the car was fine after all as is bot valve blocks.

I'm no use with mechanics at all. and don't have a clue what could be causing this problem. Has anyone else encountered this issue.

One thing is for certain unless the pressure switch is faulty it has nothing at all to do with the valve block. The compressor is not controlled by the valve block. You must treat the EAS as two seperate entities. Compressor circuit, air generation and storage. Valve block, air distribution. If there is no air the valve block cannot distribute it. Sounds like the compressor has failed, concentrate on that first of all.

google the 'pigtail method air suspension' you should get a link to rangerovers.net. This will instruct you on how to operate each individual component of the system using pinouts from the ecu connector.

I'm with wammers though as the only things that will stop a compressor are the pressure switch and thermal cutoff switch.
Also I wouldn't touch the EAS without fault code reading ability. Have you the free software and lead?

The compressor will not run if there is a hard fault logged. I can supply you with the EAS cable and software, look at the for sale section
