TD5i - Deflating Rear Suspension

Does anyone know of a fix for deflating rear suspension ? It is not a linear deflation, so I don't believe it to be a conventional leak.
Sometimes it can deflate within 2 hours of use, usually it requires an overnight period, but occasionally it remains normal for up to two days.
I'm guessing there must be some sort of sensor problem or something but I'm hearing rumours that this is not an uncommon problem?
I'm a newbie to the site and have always been a Landy fan (Had this one from new and Freelander previously) but I have had serious issues with both vehicles and find my humour levels beginning sag as fast as my suspension!
Not afraid to get my hands dirty, so I'm keen to fix this myself if at all possible. Can anyone point me in the right direction?
Cheers, Craig

normally its the air springs that go porous, set the suspesion to off road mode, switch the engine off then crawl under the back and spray the springs with wd40, if they're leaking you'll see bubbles

Hi Clutchdust

You're on the money.......leaky air spring.

Took it in for repairs and the drivers side window fell into the door on the way there....broken regulator...........oh the joys of LandRover ownership !!

if and when I climb in the rear of my land rover when the engine is off the suspension deflates. Not a clue why!

Not that difficult to replace if you into DiY.
Decent jack and stands and a few hand tools is all you need. Couple of hours will have you right. Think I paid £100 the pair for Dunlops, they came with instructions.

Could be going into access mode if door is open, but more likely leaky spring. Inflate fully and spray with soapy water, bubble = leaks.

It's good that you are replying to a year old post on a 17 year old thread in the wrong section.

So don't leave me hangin'
What was the problem ?

Too many pies probably.
