Talk to me about the LR3

[Eniam17]

^^^JimBiram, when you blew head gaskets at 123k had you ever done any cooling system maintenance such as flushes, etc.? How many years into ownership was that? I am kind of surprised to hear about the blown head gaskets in the LR3 at only 123k miles.

2nd time was three weeks ago when my height sensors threw a fault that could not be cleared, and had to be towed on flatbed 200 miles. (Thank you AAA Premier!) Cost 1,200 at dealer for 4 sensors.

I am 99% sure you could have trail fixed this with just a little more knowledge.

1. Move to the flattest section of ground you can find.
2. Use the IIDTool to clear the fault to get the compressor to kick on
3. When the suspension has returned to a full height (or a height you think is acceptable), Pull 2 fuses from the under hood fuse box that control A) The air dump valves and B) The terrain response system

By pulling the fuses it will prevent the air dump valves from every opening (trapping the air inside) and with terrain response disabled it won't yell at you for the faults.

If the height sensor is soo out of whack and immediately throws a fault when you try to clear it with the IIDTool, look on your NAV 4x4 info screen to find the height sensor that is off, then jack up that corner of the vehicle (Or disconnect the height rod and manually move it to a position where the fault will clear).

I have always been able to get a rig back up to an acceptable height when a 'dump to bump stops' fault is thrown, and I offroad with 90% LR3's so it happens from time to time.

Great info. Mack73, thanks. Is there a workaround for if you don't have NAV to know which height sensor is the culprit?

If you have an IIDTool then yes you probably could. Use the IIDTool to view the live values of the height sensors, it should be obvious which one is not like the others. I haven't tried doing this but I don't see why it wouldn't work.

At this point, the wife and I will be keeping the H3 until such point we need greater towing capacity, then I will look further into the LR3 or Ranger Rover

I did a radiator flush on the system around 70-80k miles, so I didn't expect to encounter a problem like this. Turns out that the radiator had about 30-40% blockage, despite the earlier service. So I'm flushing radiator more frequently to prevent this in the future.

You know, those are all good suggestions. We did nurse the truck to a level spot, hard on bumpstops. Using my IID Tool, I cleared the faults several times, resulting in the compressor starting for about 5 seconds before the fault occurred, shutting off the compressor. Then we pulled the relay that controls the compressor and put in a jumper, which allowed compressor to start and run continuously, and while that was going on, I cleared the fault again, however the compressor would just run, and the truck did nothing...no lift at all. The Tool told me that the two rear sensors were the culprit, and we attempted to lift the truck with my XJack to check wiring, etc with the sensors. No luck. I'm now convinced that they had shorted out, due to the large amount of water we had been driving through earlier, and age. When the dealer replaced all four sensors, the truck lifted right up like nothing happened! Now I have 4 sensors in my kit for the future if this occurs again. The Tool was and is invaluable, yet when parts short out, you need to replace it. Thanks for the tips, though, and will keep in my repertoire of trail fixes!

Amazing information. I'm glad that with a bit of know how, an LR3 can be fixed with the proper tools.

BTW, once you do this, and get it off the trail, then what? With terrain response, I take it the traction control doesn't work? Can you rear diff lock (if equipped) be used?

In my case the other systems didn't matter because with oversize tires I could barely crawl without rubbing tires or avoiding brush and rocks underneath. Lesson learned...at some point around 150k miles, more electric and moving parts are just going to wear out.

In regard to oversized tires and a spare, there are aftermarket swing-a-way tire carriers for the LR3.

This is the reason I spent a bit of money to convert my brakes to fit 17" wheels. The key is to stay on a 31.5" if you want to try and drive on bump stops. Won't be pretty but atleast it will roll without damage!

I still find myself wishign I had considered the LR3 before. I jsut never gave it a second thought since at first glace with IRS and luxury trimmings it did not seem like it would be a good rock crawler. My biggest pet peeve is the darn stupid big rims and low profile tires. Rocks and rims don't mix.

For those of you who are still within your warranty period, check your dash carefully. Mine started to split on the airbag seam a couple weeks ago. I'm within my extended warranty, but not the factory warranty. I asked them to check it out and see what could be done. Unfortunately, it's not covered under my extended warranty, and a new dash would cost about $2K. They told me this is a common problem, happening even more regularly in the jags. Hopefully LR will recognize the problem and offer a remedy.

I have the same issue on mine getting worse each day.

Hi Mack,

As an owner of an LR4, I found your tips extremely useful! Thanks .

Do you have the schematics or cloud you explain which fuses are for the air dump valves and the terrain response system.

Best, Michal
