hi folks I know it not a p38 range rover.
my 2010 3ltr disco 4 is bringing up suspension fault it looks like the front has sagged down.
now I presume it would be the same set up as a p38 as it on air bags front and rear.
so was wondering is there a way I can put air in the system to check if the air bags are leaking?
could I also be able to check air pressure from the compressor
thank you for your help

No idea. However, a mate of mine has an L320, which is basically a Disco in a posh frock, and his was dropping on one side at the rear. He bought a replacement air spring, fitted that and it made no difference at all. Still dropping. After a bit of Google and Youtube research, took the rear valve block off, took it apart, cleaned it out and replaced the O rings. No more dropping. Although some people complain about the push in fittings used on the P38. the L320 has screw fittings but they are such a pain to get to, they have to be undone half a flat at a time. Although a pain of a job, he has the advantage of having a 2 post lift so could get it up in the air, I suspect doing on the ground really would be an arse.

thanks Gilbertd
I knew the 320 was a posh disco will have a look tomorrow and see what's going on

A leaking bag would cause it to sag but wouldn’t cause it to display a suspension fault on the dash.

You really need to get it on diagnostics and read the codes from it. You could try viewing the 4x4 info screen on the dash to see if one sensor is out of range though.

Although on air, they are very different systems to the P38, you’d be better asking on disco4.com.

thanks David
got a code reader will have look see what comes up with.
sadly mine doesn't come with the info on the screen as it a GS model so it basic radio settings on the screen

hi folks got code C1A36 poping up electrical monitor.
General electrical failure.
could this point to a blocked vent valve ?

all fixed today had compressor off and found a broken wire on the solenoid other vent

Always nice to hear the problems solved. Thanks for sharing the solution.

that's ok the wire had rubbed on the casing looks like when it was last fixed or replaced the wires was pushed out the way properly
