hi all, my car is starting to sagg on the rear passenger side corner when it has been turned off for a couple of hours.
i think it is a leaky air spring and can get them cheap second hand but how can i depreasurise the eas system without testbook to fit and remove the springs ?

Jack vehicle up place stands under chassis allow axle to hang. Take drain plug out of air tank to depressurise. Change spring, replace drain plug, put vehicle back on floor. Start engine. As long as ignition is not on vehicle has no idea what you have done.

thanks for that i will have a look on rave for the air tank drain plug.

Just follow the instructions in RAVE. Other than the testbook thing. If you need to remove a shockers to get axle down enough don't forget to disconnect height sensors so as not to strain them. And to connect shockers and sensors back up BEFORE you reinflate suspension.
 
you don,t need to.bring it down to mine and stick the laptop on it,and i,will depresurize them for you in 45 seconds,do your repair,ill run a full eas diagnostic for you,then you can go home happy;)
 
No need for Testbook at all,jack the corner up you are changing,open a door then stick a knife in the air spring.(Careful now,and only after a risk assessment.) Change the spring,lower the car to approx ride height,fire it up and shut the door.You may need to remind it with the rocker switch but thats it.Using Testbook to depressurize just makes a load more work for the compressor to do.
 
Good on yer eightinavee, drastic but highly effective. Safer than trying to remove a plug with 140psi behind it, even though it has got a relief groove in it. You can of course disconnect the push in fittings at the valve box, holding on to the tube to prevent it flaying about.

Not really drastic,just quick - the margins are so low on these jobs the quicker I can get it off the ramp and onto the next job the better.Sticking a knife in it also prevents bin divers from using a badly worn/perished bag again - its not very good when they burst on the road.
 
OK, let me jump in here too. Pour a big puddle of petrol on the ground, drive your rangie right over it, hop out and light. After you've heard the 4th airbag pop you can get in and drive your rangie out of the flames - if you can get in and if it drives. Fit steel springs. Nuttat will ever go wrong again even if you do park right on top of a flaming puddle of petrol.

It is actually quite easy and there are several methods - the easiest of which was sort of mentioned above: lower the suspension to access height and then jack up. Unless you're planning on replacing all bags, don't let the axles dangle. The volume change will take care of about 90% of the pressure. You can also use jumper wires at the valve block or eas ecu connector - check rangerovers.net - air susp. repair pages for the proper pins.

Sorry, but after reading this thread, I had to rant a little.

So what upset you ?
 
All I did when I fitted all 4 airbags, was to push-in the ferrules on the pipes going into the valve-block, whilst holding the pipe & slowly 'easing' it out of the housing, by doing this gently, the air in the system will 'pfffffsssttt out! But remember that the car will drop as you do this, so keep well away from the falling bodywork!!
 
Nothing quicker than depressurising than a good knife or 12mm drill bit. That's when you discover that adreniline is brown and runs down your leg!!!!:bolt:
