P38 air suspension
thermidorthelobster:
Make sure you drain the air out of the system before you disconnect anything. Undo the drain plug at the back of the reservoir under the sill below the driver's seat. As it loosens it will let air through and the system will depressurise. It won't fly off at high speed as the pressure is released before it gets to the end of the thread.

Found the diagrams for removing comp / air springs on rave
When you pull the outlet pipe off the comp to remove it does the air escape here or is it just like taking an air tool from the hose with no leaks
I'll try your sook test (oo'er missus !) at the weekend
It seems to drop down offside rear first then offside front - nearside stays up fine
When system is back to normal it rides even with no lean
Everything seems to be pointing at a leaky airbag - ok to do just one or do they need done in pairs ?
If I have to replace them all AND the comp I might as well bin the lot and fit coil spring kit !

Its okay to just do the one,although if ones started then u might need to replace the rest,personally dont bother with taking the bung out the tank,its far to much fafing about & have u ever tried to get it out?
just use a 10 mm spanner & whip the outlet connection of the compressor,ull get a squirt of air nowt much motor prob wont even go down as ur not disturbing the valve block.
when uve swapped the comp over start it up n leave it ticking over for 10 min with the drivers door open,this will charge the system,close the door & it should rise up

at approx £80-100 for a bag & £100+ for a comp id personally stay with the air,
if the bags are perished & the pump is a bit tired its a crap ssetup,get it all working good & its a brilliant set up
thermidorthelobster:
You can buy OEM air bags as well, in fact they're from the same supplier but a lot cheaper than the Land Rover genuine part.
If it turns out to be the valve block, then for the sake of a grand or so, you'd probably be better off financially with the coils... but I always think it's a shame to lose the air suspension as it's part of the charm of the vehicle.

valve block rebuild kit- about £15 :wink:
www.rover-renovations.com cant recommend that guy enough- just remember customs/VAT. you might get hit with it, you might not
I rebuilt my compressor with the kit by the way, very easy. Stupidly, i just swapped the compressor over for a new one thinking it would solve my constant running problem but it didnt (i've got a leak somewhere) so i've got one sitting around (minus mounts)
loads of instructions here www.rangerovers.net
Dont convert to coils, good luck
