Air bag suspension is not working on 2002 land rover. Dropped to bump stops and the EAS light is on the message center reads 35mph max speed.

By bouncing, do you mean that system is raising and lowering the vehicle or do you mean you feel like you are driving a clown car through a boulder field? If the first, you have a height position sensor(s) that is failing or failed. If the second symptom, your system has de-pressurized (which can be caused by a number of things) and you are bouncing on the "bump-stops". These are pushing mounted on your axle top that prevent the vehicle from dropping clear to the ground. Happy to provide more suggestions if you would like to post more info. In any event, if the orange row of lights on your dash panel EAS switch begin flashing this is the FAULT mode and you need to stop and park vehicle asap if you do not and you continue to drive the vehicle you will eventually go into HARD FAULT mode. This is indicated by your dash message center reading "SLOW 35MPH MAX" and you do not want this to happen. The hard fault takes you to a BeCM (rover's brain) state that requires special software, electronic tools and know how, and sometimes alot of patience to cure OR usually about and hour of shop time at your "TESTBOOK" equipped LAND ROVER dealership service department to correct. Good luck.

Stop letting people talk you into cr@ppy springs - the vehicle has a EAS for good reason.

After checking the air tanks and air lines for leaks do the following:-

1- get a new compressor or get a compressor repair kit plus a new relay switch - easy install + if that works - fine, if not
2- purchase new US made air bags from Arnotts and check the struts when replacing the bags - if that works - fine - if not
3- check & replace the 4 EAS sensors.

The only other fault could be with the computer module itself.

installing springs is a loser's fix - you might as well just go buy yourself an ox wagon.

For many repair operations you don't want the suspension to be adjusting itself up and down while you work on the vehicle. Classic air sprung models have a disable switch under the seat, but this is lacking on the 4.0/4.6. On these models, the following options are available for disabling the system:
1. Leaving a door or the tailgate open effectively freezes the suspension
2. Unplug the air suspension delay timer, a small black box that looks like a large relay under the drivers seat.

Problems with the air suspension seem to be less frequent with the Sport than in previous Range Rover models, but they still do occur. One owner reports "Whenever my RRS is lowered to "access" level a suspension system fault message apprears.". Another reports " Had the RRS back less than 2 hours and another "suspension fault." Also kept receiving messages that the vehicle is raising slowly and vehicle will raise when system cools. Couldn't even drive because it wouldn't raise out of access mode. Anyway, back to the dealer. Picked the RRS up again today-dealer said the EAS compressor was faulty and replaced it. So far everything is ok." Overall, most of the problems seem to be related to bad suspension height sensors or bad compressors. Angus Wade of the Czech Republic had his suspension light come on when in Germany; it started yellow and then red, then disappeared when he stopped and restarted the engine -- and has not happened since. His dealer said they have seen this a bit.

Weak Compressor: An official Technical Service Bulletin (TSB) LS-204-004 addresses "ELECTRONIC AIR SUSPENSION (EAS) WARNING MESSAGE AND LAMP ILLUMINATION". This deals with the warning message "Suspension Fault - Normal Height Only" message appearing with the Air Suspension Warning Lamp on. Computer diagnosis shows pressure increasing too slowly or unable to pressurize, with no air leaks. The usual problem is the compressor exhaust valve sticking, causing an internal air leak when the compressor is active. The bulletin recommends renewing the air compressor (RQG500090 is the latest specification air compressor with a stronger exhaust valve return spring)and installing and updating the air suspension control module software using WDS disc 13 or later.

Suspension Fault Message (random): One owner reported getting random suspension fault messages on his brand new RR Sport purchased in June 2006, well after the fix was in for the weak compressor. His suspension Fault message and Suspension Warning Light (Amber) came on after 5 days of ownership. He stopped and restarted the car, which caused the light and message to disappear, but they came on again after 5 minutes. Later the same day, the warnings disappeared again.

I have heard that on 2006 models, EAS fault messages can be caused by an internal leak in the Air Suspension compressor exhaust valve. The fix is said to be replacing the compressor updating the software.

Hope helps.

Welcome to Fixya

Air suspension is currently in fault mode. It will have to be re-set by someone who has the Land Rover scantool (either a dealer or an independent shop). The EAS system is inaccessible with a regular OBDII scantool. The car will not allow you to control the suspension height (raise/lower/defeat) until the fault is cleared. Please see this link .

Thank you for using Fixya!

The EAS system can only be entered by using Land Rover T4 testbook , at an official dealer. There , they can check what is happening with the EAS system and then offer you a quote on how much it would cost to repair. SIT DOWN when they tell you the cost !!!
From day one, when Land rover fitted EAS systems to their cars, back in the e 80"s, they were useless, always causing problems, and very expensive to repair, but they continued to fit them to this day. If you are going to keep the car, i would strongly recommend that you have fitted a conversion kit, which consists of springs, mounting brackets etc and an electronic unit that switches off the existing system , so you dont have warning lamps illuminating, so then the suspension becomes conventional spring and shock absorber, The ride is just as good, more reliable , no electronics to play up etc. Call your local independant land rover specialist for a quote. It really is worth considering. I have converted many Range Rovers without any problem and very satisfied customers. cust Hope this helps

eas works with 5 valves,compressor,
compressor works?(in the box left side undernhood,)there is als interferance with dooor switch,if one door open,no position change possible,
the message on dash is eas malfunction?,
opn compressor box,if nor running compresor,shake or slight hit,
reset to 0 position?,shut contact,take off relay for compressor,disconnect wiring on compressor(main,)switch on again,now place back relay,connect again,while contact on,wait some minutes,reset is done,cut contact,on again,and see the for message,

The EAS can have many different faults that will give the same warning. I have had several air susp problems. First try to disconnect the battery, wait several minutes reconnect then drive car making at least on full circle. If lights remain, air pump (under spare tire ) can be checked, also valve under a cover behind right front wheel, other than these areas, the Testbook diagnostic at dealer will determine if any other parts are source of problem. Unfortunately, with the complexity of the system many other parts Height sensors, etc, etc can also cause the error message. Good Luck.

you can try turning the ignition on and off , only to position two ond off with out starting , between 20 - 30 times this sometimes confuses modules and causes them to clear faults , if not i would recomend getting it plugged in , if vehicle is not in warranty go to landrover specialist , much cheaper!!!!!
