air pump running alot
automania:
right took the pump apart and the seal on the piston was gone so got a kit of the bay and it works now, however stilll runs a lot tho, so im persumin there must be a leak somewhere. how often do these pumps run generally? cheers
Range Rover Blues:
I'm not sure if you can isolate the EAS on the P38 like you can on the classic but if you can then leave it in high mode and isolate the system, leave it as long as possible and see if one corner sinks, that will give you some idea where to start.
It's all well and good the manual saying use soapy water but with 10 years of crud on everything you won't see a leak straight away. Check pipe runs for chafing and obvioulsy unions for leaks, they have 'O' rings which can harden over a period. Also the valve blocks use 'O' rings as valve seats and these too go hard.

You can isolate the EAS by pulling out the tall relay located under the passenger seat - leave this out overnight and see if a particular corner has dropped
Check all your air bags and pipe connections - especially where they enter the valve block for leaks ( use a spray bottle filled with water/ fairy liquid, and look for bubbles) Test the air bags at ALL heights as they can sometimes only leak on a particular height setting, chack for cracks/perishing around the bottom of the bags too
automania:
im thinking somehting in the valve block possibly the o rings mentioned above, reasoning behind this is the car will stay at off road height all nigh without dropping and all the bags have benn replaced. when the engines running and the cars stopped i can hear the valves clicking and adjustig it, this can happen every 20 secs or so.
on another note a had a eas kicker plugged in the other day and it showed up three faults two were the front height sensors being out of range and the third came up blank. now the faults were cleared, but does this fix the out of range problem? or will the fault codes have come back now? cheers
v8kenny:
The clicking is fairly normal, especially if you park on a slope - the suspension will level itself every few hours right through the night - this is why you have to pull the relay under the seat to try and locate what corner is leaking
Sounds to me like you need to recalibrate your height sensors - the kicker will only have cleared the faults, not calibrated, although I do beleive you can calibrate with the kicker - not sure of the procedure as I changed to coil springs ages ago ;)
If the O rings in the valve block are leaking you can buy a DIY kit to refurb them from the states - I have one lurking in my shed somewhere if you are interested
