P38 Range Rover EAS Air suspension problem

The timer relay is the one under the front passenger seat.

I have been speaking to a chap called simon today who sells EAS parts on Ebay and he has mention that I need to fix four emergency valves to the valve to check the pressure in the system at a cost of £112.00

HOW MUCH?? How will these check the pressure in the system? I suppose it would let you connect a pressure guage, but I don't see how that would help as pressure doesn't seem to be your problem - if it was then it would drop overnight, not when you start it. I wouldn't expect to pay more than a fiver for them.

I've got some fitted to mine and they're an absolute pain in the proverbial. A constant source of leaks. They're going in the bin next time I do some work on it as I've never found any reason to use the stupid things.

I will jack the bastard up in the garage and fit coil springs on it. Job done.

Don't do it - You'll regret losing the flexibility of the air system and I understand that it makes the car dangerous as the airbags are too far inboard to allow safe replacement with coils.

It's amazing how many 'helpful' people there are out there wrt the air suspension. Funny how most of them want to sell you bits. It's no wonder it's got such a bad reputation. Stick with the experts on here!

Problem solved for now I hope and thank you for all your suggestions and insults on my EAS problem, all to the next time.
Ordered a new compressor seal kit off p38 spares website for about £30 including P&P, Strip the EAS compressor apart following the instructions and pictures posted on this thread thanks, piece of cake. All the seals inside were non existent, I was very surprise that the compressor was able to create any pressure at all. Also blue air pipe leading from the compressor to the valve block was loose and leaking air.
Also replaced front drivers and front passenger door locking solenoids the other day RCL was not working and now its all working just sweet, So if you want a job doing properly, do it your god dam self.
I was showing off my new toy off to my mates last night and one of them said owning a range rover is a bit like having STD, you have a great time getting one but its a f**king nightmare living with one. I said that I remember that when your stuck in the snow in your little matchbox/death trap of a toyota yaris screaming out for a tow and all that you beable to hear in your thoughts is the sound of my laughter ****er !

Regards Dave from Coventry that ****hole in the west midlands.

I stumbled across all the very useful information posted on these pages and it caused me to think about the very bumpy ride I've been having with my 2001 Caingorm 4.0. Having never driven a RR before I assumed it was just the terrible Glasgow roads that were exagerating the rattle.

Is it possible to diagnose what the problem is. Having read through all the information I am convinced that it is an air suspension problem but am struggling to know where to start. Is there anywhere near to Glasgow that someone could recommend I visit for a diagnostic? Am understandably reluctant to take to a RR dealership.

Why not get yourself a diagnostic cable, build it or buy it, plenty of info on here how to. Download the software it freeware, and fix the problem yourself. it as easy as!!

Bumpy ride is more likely shocks than the air suspension, so putting it on a diagnostic is not going to tell you anything

Many thanks - I have ordered one: eBay item #370290702246 Air Suspension Diagnostic Cable - Range Rover P38 EAS.

From doing a bit of research I think my situation is that we are riding on the 'bump stops' - constantly! Does the air suspension raise whilst driving or do you need to let it raise fully before setting off? Seems bizarre if the latter.

It may we be that the car has always been resting on the bump stops and never fully raised. I always drive straight off!

If I could find a fellow forum member in Scotland that could give advice that would help!

Dr Paul.

OK, we must have posted at the same time - just seen the comment about the shocks. If I get the diagnostic tool and then post the results we ought to be able to identify whether it is indeed the EAS or not.

If the shocks are the guilty party then I presume these can be sourced also?

Dr Paul

Parked on level ground it should stay up and not go down to the bump stops unless the system has a leak. If parked on uneven ground it will continue to try and self level after you have parked so will drop, but not to the bump stops. You should let it rise before driving off if it has gone down, only takes a matter of seconds if all is working as it should be.

OK, I do see the suspension working. The lights on the 'dash' appear to flash as it apparently raises up. Makes no difference - the ride is always very shaky. When the RHS wheels pass through a pothole the whole cars seems to rattle with a very hollow sound indeed.

Dr Paul

I've checked out the Air Suspension and it moves well from High to normal to low (when parked). I used the vehicle on 'high' today out driving and the rattling still persists. I assume it must therefore be the shocks.

Hi all
I'm having constant problems with the EAS suspension on my 1994 Range Rover. Driving along happily, first the "EAS fehler" comes on the dashboard with the arrow pointing under the car - then it falls to the lower level and I kangaroo to the garage to get it reset. Any ideas most appreciated.
Best wishes

If it's happening frequently then there is a fault somewhere causing the error message. All the garage is doing when they reset it is to clear the fault, not solve the underlying problem so it will keep triggering the error state until it's fixed.

Ask them exactly what the fault message is - we can offer suggestions based on that.

If it drops to it's bump stops, it means it's got a hard fault. Not that this helps you much!

Hello there
I have recently bought a 1999 T Range rover DSE and I have notice that the air suspension is playing up. What is happening is when I start the car up in the morning it is set in loading mode with the normal ride height button flashing after about 10 minutes driving around in the RR the loading mode light goes out and the normal ride height light stays on and the air suspension works fine, up down no problem. Even when I park up the RR overnight it still remains at its correct ride height. As soon as I get in the car again in the morning and put the key in the iginition and start her up, I can hear air being release from the compressor and it sinks down to loading mode again with the normal ride height light flashing and the whole process repeats itself. My Range rover is currently in the local workshop, One of the chaps down there have check it all out for me and they said there is no error codes showing up on there computer and the compressor is working fine. So it may be a leak from some where but they don't know so I don't ?
Any ideas would be most appreicated thanks Dave.

Compressor maybe running but that does not mean it is giving good air pressure. Sounds like you have a leak on the pressure storage side and a duff NRV2. Air leaks from pressure tank overnight, if NRV2 is duff when you switch on and system opens inlet valve and bag valves to inflate bags, all the air from the bags flows into the air tank. Then you have to wait for compressor to build pressure to inflate system.
