Can you give some idea what's wrong with it, some symptoms you can fix yourself and the ecu resets. probably lot of fellas on her could give some pointers.

hi there, well i bourght it with a manual pump up system,
it is on full lock, 35mph max is showing and all ride height lights are on,
many thanks nic

it needs to go on a diagnostics system any landrover dealer can do for about £40-£50 and that would tell you what the eas fault is and reset it but you might need to buy a bit that caused the fault if its at fault

What type of manual pump system:

• pump up with garage compressor.
• Pump up with eas inbuilt pump by some type of override switch
• do you have to pump up each bellows seperate.
• does one or all corners drop over night or over some days
• what you mean, is on full lock.

hi there, yes i have to pump up with a garage compressor,
and it all drops down overnight,
and full lock being where the ecu completely shuts down the system
cheers nic

Well you don't need a garage to tell you that you've got an air leak.

That might not be all that's wrong with it, but it won't be helping and could easily account for the fault condition.

cheers, will a diagnostic test tell me exactly what else may be wrong with it??
do all air suspension systems leak a little bit?
the back goes down over about 1-2 days and the front about 3 days, major leak???
many thanks nic

You need to give more info on the pump up system as its configuration will give us some more clues, there are many types available. some, you have to shut off each EAS airline with little valves somewhere and pump up individual lines - one at a time. Others you can pump all four up at once. As Kooky-guy is alluding to, it could simply be a leaking O-ring or a bellows, but maybe something major.

yip i have to pump up one at a time, whats the best way of finding a leak??
cheers nic

Ok, from what you've said, it sounds like a small leak - mine goes down faster than that, but it's supposed to be able to stay up indefinitely.

Does one corner go down faster than the others? If so, that's a clue as to where to start looking for the leak. What sort of condition are your airbags in?

Are you wanting a garage because you have no interest in fixing it yourself, or because you don't know how?

What you say doesn't sound like fast leak, so hopefully pump is still OK.

Get yourself one of those atomiser spray bottles put in some dishwashing liquid and water, mix consistancy to make bubbles, pump up each bellows and spray all over where air line goes into top and all over bellows, do only one at a time and look for bubbles forming, **** of a job getting to top where air line is at back but the rest should be easy, do all four. If no leak found wait till it drops a little, then repeat to bottom of bellows only, one at a time, cause sometimes, depending where splits have developed they can close up and become almost air-tight and hard to find. Keep repeating in stages as it drops until you find leaks, because they're there. If it's air line leaking, could be simply not fully seated into fitting, or the O-rings failed, some times if you remove the air-line, lube it with a very thin smeer of the mixture you have in bottle it can seal them. If it's bellows - self explaining really. This should be a good area to commence at and an area that is simple and reasonable to fix yourself. Sort this first then let us know the outcome, then hopefully, some one here can then take you through the next stage.
