Range Rover P38 EAS Problems, Help Needed.
Discussion
Hi, Please redirect me if I'm asking about this in the wrong area but it will be a start.....our family have been running a 1996 4.6 RR hse for the past 10yrs as a tow car. 30K ago it had a new "crated" V8 and was converted to LPG. It still runs great but we now have a problem with the EAS in that we have the dreaded "35mph Max" warning on the dash and the suspension is down on it's stops. Whilst this may be a straightforward fix (dependant on the problem ie pump/bags and so on) we dont want to spend a fortune on diagnostics to find out it's to far gone and ready for the breakers. So, the question is are there any piston heads EAS experts in the Worcester area who can can give us some guidance?
Shame to scrap it as it's been a good servant that still looks the part and goes very well, thanks in advance. Chris.

Does the compressor pump come on? (located on n/s chassis leg - it will hum/buzz when you start the engine).
Does the suspension raise/lower?
Is the body resting in the bump-stops? (very hard bouncy drive) [edit: yes I see you mentioned that it is
]
Lots of info on http://www.landyzone.co.uk/lz/
Look in to an "EAS Kicker" tool... There will be plenty of people on Landyzone who are willing to help and possibly someone in your area who will have an EAS Kicker.
If the suspension compressor kicks in (as mentioned above), spray soapy water mix on the suspension air bags and look for bubbles indicating leaks. Airbags are no longer expensive.
You could have seized potentiometers too, which help control the suspension.
There is a main fuse inside the suspension pump housing. Check this.
Other than that, an open tailgate I think instigates the 35mph lock - from memory - so it could be a sensor here even.
Start with the compressor pump and work away from that. Whatever though, you will need to reset the fault code. You can download the software and simply run a lead (available from eBay) from a lap top directly to your car. The plug is in the passenger footwell under the dash.
Software here - if you can make a lead this will be quicker:

Lead here (with software)

Good luck - should be fixable as it's the labour in diagnosis coupled with the fact that people are scared to touch it!
Last resort a dirty fix would be a coil spring kit - but that's nasty IMO.
