I am fed up with the EAS and am going to bite the bullet and convert my (her) Rangey.

Apart from Rimmer Bros, is there anywhere else I can go to source the kit/parts?

Is there an easy way of fooling the ECU that the suspension is okay after you have done the conversion?

Thanks

Rich

Most of the kits come with a doohicky (technical word) that plugs into the EAS ecu (I think sometimes via the height switch on the dash) that fool the ECU into thinking everything is ok.

I persevered with mine, new air springs, new air pump, re-built valve block kit and a couple of sensors. It's great now in a waft-tastic way and reliable, too.

Bear in mind the P38 wasn't type approved with coils so there may be a construction and use issue when you use it on the road. Tell your insurance company, too.

Mine is going to need new bags (airsprings?) and a new pump before long, the cheaper option seemed to be fit and forget coils.

Ahh, good old Aunty Ebay is your friend here. Springs/bags are about £65 each and a doddle to fit, the pumps are £230 (although I have seen pump repair kits for much less, but they just seem to replace piston parts and don't touch the electric motor side of the pump)

Ebay shop, nuffink to do with me!

Although it would be a touch more expensive to do it properly (I think the coil kits are about 350 quid?) you should get another 10 years/100k miles of floating on air out of them.

Pump repair kits are about £25.They ride terrible on coils.The roll in some corners can be intresting.

£85 tops for a full compressor repair kit including piston. £65 a corner for air springs. If you want a big 4x4 on coils that handles like crap you'd be better off with a Shogun rather than ruining a Range Rover.

Update!

Have taken your advice chaps and will have a go at replacing the airsprings myself. Seems a fairly straight forward job, providing I use my common sense.

The compressor is still working okay, but because of leaky airsprings is working much harder and getting hot. Guess new airsprings will allieviate this and prolong the life of the compressor, so not such a major expense all in one go.

I spent £1600 and still it went to drop to bump stops every now and again(EAS message). Gave up(with main dealer !!!) and made a gizmo so i can raise and lower the four corners at my choice, no ECU to control it. Shame i wasted the money though !

LR list the airbags as having a replacement life of 10 years anyway.

Ive done this conversion a few times. it is expensive but dont be tempted to buy the bits seperately as you will never get the elctronic faults to stop bleeping at you!!!, and you will be hard pressed to get the spring rates right.
The best kits are from the states and is a spring and shock set made and developed properly for the 38A Range Rover, it also comes with the spring plates and.... an electronic ecu thats fits into the loom and stops the eas from thinking its faulty.
drop me an email and I will give you a price.

Cheers Roy
