I'm very curious about the final fix. My 05 LR3, 156K miles, has been having similar problems. I plan to do a compressor rebuild before I drop the cash for a new one. Although buying a new compressor is inevitable maybe a rebuild will buy me some time.

 

I was driving in town yesterday and all of a sudden the red EAS warning light came on and then the message to not go faster than 30 mph and special programs not available. It lowered all the way to the bump stops. I limped home and let it sit overnight. This morning I did a hard reset with the battery cables. I started it up and red EAS light was still on, no special programs available, plus the compressor does not come on, totally silent.
A little background: 2007 LR3 SE, 156k miles, oversize tires (285/60 18" Nitto Terra Grappler G2s), 2" lift (Proud Rhino), alignment with lift kit.
Any ideas on why compressor would not come on?

 

Have codes run, check fuses. Because you're running the lift with those size tires, check the wiring looms running near the wheels, you might have tagged a sensor or rubbed a wire?

Have you had any historical water ingress with your 3? Any water inside after heavy rains?

 

Thanks for the quick reply DavC. Have never had any problem with water ingress since I've always been aware of that and the related problems. Only other thing I've noticed is it would occasionally lower the front end while waiting at a stop light, but I thought its normal for it to self level at times. I will check the fuses today, but I'm not sure about the wiring looms.

 

AFAIK that behavior is not normal. Only time my vehicle levels is when I turn the engine off, get out, close the door, and hit the lock button on fob. Then it releases some pressure and generally comes down by a few milimeters at rear (this is apparently related to the suspension adding a tiny amount of height after a certain speed is reached, IE freeway speed).

If you're really lucky maybe its a faulty or blown fuse. Maybe the sensors are not calibrated correctly? Maybe you tagged a wire as said before. Apart from that maybe you'll have to bite the bullet at some point and get it diagnosed with a good tech at LR. Mine have always done me right and solved a few persistent problems I couldn't fix myself.

 

As far as I know, the only types of EAS faults that come up red and limit your speed are Cross-Articulation faults and "dead-compressor" faults and only the latter result in the compressor not functioning or at least trying to function.

....but let's clarify, do you mean that your compressor was silent WHILE the fault was active? Like the red icon was lit, you were on bumpstops and tried to select normal and it did nothing? Curious what the compressor would do if the fault were cleared.

Anyway, check your wiring loom in the driver's side front wheel well (on frame rail). If that's intact you need to get your calibration and compressor checked. I would maybe try that hard reset again. If you can get the fault cleared or the compressor to run, then as soon as the suspension is up, pull the EAS fuses. Then you could drive it (slowly and carefully) to your dealer or mechanic.

Otherwise it's tow truck time, and maybe that would be better anyway.

 

hour_wa - Thanks for your reply. I did the hard reset connecting the battery cables, which I'm sure worked because the clock was reset to 0 when I started it. However the red EAS fault was lit up, special programs not available, and of course it's still on the bump stops. I got down by the driver's side rear wheel and did not hear the compressor running. I'll check the wiring loom and the fuses, but I think you may be right about it being tow truck time. Luckily I have a great indy LR shop, North Texas British, here in the Dallas area.

 

So, here's my update... I have my LR3 back and it's got a new AMK compressor. Sadly, I still have a leak that appears to be originating from the front struts. I might take it to the dealer at some point in the future, but as long as I start it up once a week then I won't have an issue of it hitting the bump stops.

With the 2 inch lift and your truck being empty of air your sensors are most likely falling out of range which disables the compressor and gives you a red EAS fault. This is what happened to my truck with my own Hitachi pump. Once the truck was on the shop's lift and raised up the compressor started working again.

 

Adjustments after coming to a stop typically mean a bad height sensor, the shifting weight caused by braking changes the height of your vehicle and the faulty sensor confuses the computer so it tries to adjust your height. When the sensor finally completely fails, it will trigger a red fault and lower your car to the bump stops

 

That sounds about right. In your future is a new height sensor and calibration. Not terribly expensive. If you have an IIDTool you can do the calibration yourself...and the height sensor change, too, actually. It's not terribly difficult.
