Not that I would ever have the cash but if you believe what you read the all singing all dancing Disco3 would not be one to take out bush. Its not often the mags actually take the vehicles out bush but in 2 reviews where this has been done the disco 3 failed to impress. in the first test It had problems bottoming out on the Anne Beadell due to the ride hight lowering over 40kph and in the latest 4wd monthley it failed to get past go with the computer spitting the dummy and going into limp home mode with no ground clearence or 4wd - damned dangerous thing to have happen out bush!!
As an aside while I dont do many water crossings the test showed some damned deep water crossings I dont reckon I would be trying without a snorkle

Unfortunately, that's the way they are all going or have gone in the last 5 years.
Electronic gadgets are quite reliable but its the complexity that bothers me.
ie: what to do if something goes wrong? By the time you have the problem diagnosed and fixed, your trip is over and everyone else has continued on...

Yea but other electronically controlled vehicles dont seem to have problems (with the electronics at least) The latest vks newsletter had an article about a fender that needed towing off the canning due to a drowned puter. The prado (has a puter as well) had no puter problems -just traction issues

In all fairness, I think you will find that if you submerge the computer on any vehicle the result would most likely be the same. The Canning stock route issue was very much a problem created by the driver rather than the vehicle.

Mind you, the reason we sold our TD5 and bought a TDi to get away from 'computer' controlled vehicles.

You _sure_ the TDi doesn't have an engine management unit? And, probably, a few other microprocessors do other bits too?

It is all mechanical, there is no engine management system in the TDi. The first Defender with it was the TD5.....

True about drowning the computer on any but have you looked where it is on the Disco?? I have personally pulled one out of a shallow water crossing (second time it happened to the same vehicle in the same crossing) and then helped to load it onto a flat tray for the lift home. Snorkel on the Disco didn't help at all!!

Snorkels aren't designed to protect the EMS? In TD5 Defenders the EMS is under the Drivers seat.........

Interesting comments re TDi and TD5.
I went down the same track a few years ago. Was looking at at 130 but deliberately bought a second hand (4000k ex Rover Aust) vehicle because of the "worry" factor with relatively uncommon electronics out bush.

Ended up doing a Cooma Diesel Kit in the TDI which gave similar power as the Td5.

BTW Landy like what you've done very neat outfit!

Correct.

In TD5 Defenders the EMS is under the Drivers seat.
Probably, but I asked where they are on a Disco.
It is behind the glove box on a Commodore I beleive if that helps.

Jackaroo has the computer mounted on top of the engine, well out of water and cooled by the fan.
Unfortunately it is also heated to a high temperature by the engine. Still, it keeps on going.

When you look at the Disco you realise why they have such a shallow wading depth

Forgive my ignorance - having owned 2 discos with the ECU in the upper drivers footwell - the ECUs in both my vehicles were fully sealed and waterproof. This is not the limitation on wading depth - it will be the airintake - like many vehicles it is behind the headlight.

I have no doubt that discos and many other brands of 4wds have had to be towed out of deep water but where is the evidence that they stopped because the ECU got wet? - even if my ECUs were not waterproof, the water would not get to the level of the ECU until after the vehicle had been stopped by some other cause and the water flooded into the stopped cabin. Most petrol 4wds will have been stopped because of ignition issues not the ECU and for diesels it will be loss of traction or drowning.

Lets starting talking facts - doesn't matter what vehicle it is - was there water in the ECU because it found it way in and stopped the vehicle or did the water get into the ECU after the car stopped for other reasons - (driver stupidity) - and then the ECU got flooded.

I agree with the lets talk facts comment.

Facts:
The Landrover assist help line diagnosed an ECU problem when we spent a couple of hours trying to get it going including an ECU reset. Was in limp home mode and the limp of hundreds of KM's was to far at engine idle speed on the Hume Highway.

The Landrover dealer who the Disco was flatbedded to said that the ECU was flooded. They said they dont guarantee the waterproofness of the ECU. The tech who repaired it said e edid a really good job on it by putting extra sealant on it and it should be OK next time.

It was a purpose built water crossing used to demostrate water crossigns for driver training. 12 vehilces sucesfully drove through. Hundreds drive it each year. The Disco stopped in the middle of it when the motor stopped. I dont thing it is fair to label Disco drivers as stupid for doing what everyone else did.

The ECU that Landrover repaired was not in the passenger footwell. It was inside the engine bay on the firewall. Maybe they have several places they mount them??

garrycol,
The manafacturers wading depths i believe have little to do with air intakes. For instance in th cruiser i belive it is about 700mm which is about the hight of the diff breathers. It will always be the lowest point for everything- to much emhesis is placed on te air intakes but many 000s can be blown by failure of other gear due to watr crossings. Imagine the guy who gives high 5s after pullng a crossing with snorkle 1/2 way p the windscreen telling everyone how good the safari snorkle is only to spend 1500 bucks or 2500 or whatever on diff and T/C rebuilds

Davoe - I don't disgree - there are clearly various reason for determining the wading depth but I doubt that the placement of the ECU is a driving factor.

For HJ - I don't dispute the circumstances you raise and I am sure the ECU had water in it but was the water ingress from the splashing as the car went through the water or from when it was stopped. Also I cannot speak for later discos but the ECUs in mine didn't have a limp home mode and the ECU is reset simply by removing power from it nothing more.

Despite the considerable design care and subsequent testing which goes into them and despite their high level of reliability I don't like significant levels of electronics in off road vehicles - and I design this sort of stuff!

They are too difficult to fix in the field - we accept there are many mechanical faults which will be impossible to do a field fix on but why add a whole extra level of complexity?

I doubt that they are genuinely designed with the expectation that they will go too far off-road. The more electronics and gizmos the greater the chance something will go wrong. Will not matter too much if something goes wrong in the city but as you say it could be serious if it happens out bush.

It just so sad really that a car with so many atributes on paper repeatedly lets itself down in the reliability area.

That 2 years in a row that vehicle has failed in the 4wd of the year tests.

Hard to get away from the relative reliability and seviceability of the big Jap wagons.

You obviously don't hang out much on this forum - if you did you will see that the big Jap wagons are not all that relatively reliable or serviceable either - no better or worse than the others. All modern 4wds will have the same electronic issues.

There are a number of jap awds that disengage awd above certain speeds. There are other 4wds that will not drive when the gearbox oil gets hot etc etc etc - all vehicles have their achilles heal.

Mitsubshi = 5%

Hmmm,,,,,,,,,no Nissans eh

They had even worse things to say about the new Jeep, and while i own a Disco 2 and with 50,000ks of outback travel i've done in it, i've never had a problem we didn't fix by the side of the road (had the roll over switch activate after hitting a 2' deep trench on the road to the Dig Tree) and so far she has never let me down, i'm not sure myself about the new Disco 3 electrics either.

But it's early days and i wouldn't bag it just yet, after all this is only one problem and it's only been on a couple of occasions.

Excuse me Mr R-Back

You shouldn't sling mud at a vehicle other than your own and in view of that I'll do it properly for you.

Amongst other things I also own a 05 CRD JEEP Cherokee.

It has four elextronic management systems on it which all talk to each other and if one has a 'bitch' they all pack up their balls and go home .

Just a pack of bitchy 'Bass-turds'.

I have had the said vehicle for nearly two years and the past 6 weeks is the longest its gone withouit a dash light in some configoration or the other coming on and frightening the bee-jesus out of me.

The comment above about all new vehicles having the electronic chit on them is true and will get worse due to emmission controls.

So get used to it and enjoy.

I luv that JEEP like a mistress. Absolutely fantastic when she is puting out , but such a bitch when the hormones are out of whack.

Where in my post did i sling mud at your vehicle or any vehicle for that matter, if you know me then you should know i don't do that.

I like the new Jeep (with the exception of the Commander) and the new Disco, would i buy either, no, would i buy a new Cruiser or Patrol, no, my next vehicle will probably be a Defender.

Hi Davoe
Dont believe everthing you read and you are a brand basher . When you look at the picks in the mag which you read did you see how high the water was on the other brand vehicles . LR stipulate how high the wading depth can be with out special preperration . The vehicles can go through ONLY 600 MM HIGHT OF WATER with out special preperation. I would not dare to sugest that the editor of the mag deliberately set out to drown the DISCO3. I would not trust the mag everagain, also i would not trust the pics of the 100 SER with all that water flowinging over the bonet and half way up the windscreen it could be faked you just dont know, oh also i do not bash any vehicle brand and the ones that do could be frigtened that they bought the wrong vehicle.

yes I did there was picks of 2 vehicles I think the pathy and playdoe both with water over thebonnet whichwould safely exceed manafaturers wading depth I think a cruiser is 700mm
Many people coment that they dont trust electronics but as far as I know the last truly non electronic vehicle to come out was the 2 h donk in 89 - yep even a 1hz can be stopped dead with electronic problems I have had it happen as can any 4by running a solonoid to the fuel pump

From what I have gathered, see below :
People up the cape saw the 4wd Monthly guys drive all the vehicles very hard. They saw them hit water crossings with high velocity. Indeed, Cairns Land Rover said that the ECU was contaminated with water.
4WD Monthly were overheard on UHF CB discussing issues with the other vehicles as well. This wasn't reported.
Now, at the end of the day, the D3 should not have failed. Wiring looms and computers definitely should be driver and track proof. No doubt about that. However, the D3 was definitely the most technological car there. It is so much different than all the others. More gizmos, air suspension, the list goes on. It seems ridiculous that 4wd Monthly went away without knowing anything about the car. Did they even look for the computer to see if it was swimming? Did they know where to look for important wiring looms that may have fouled?
I know that the consensus will be that 4Wd's of this cost shouldn't break down. I totally agree. EXCEPT when the testing has been well and truly beyond what could be deemed reasonable. Like hitting water crossings at warp 3.
That being said, if the other vehicles were subjected to identical treatment, then perhaps Land Rover can still learn a thing or two about protecting the ECU and important wiring looms.
I have a Disco 2 and have taken it many a place. All without a problem except for a stuffed tyre. I would trust my D2 up at Cape York tomorrow. I know the vechicle. I know what to look for. I know not to try and kit it at high speed through water crossings. And I have an interest in the vehicle and know its capabilities. 4WD Monthly, on the other hand, had no idea on what to look for to troubleshoot. I don't know why you would take any vehicle up the Cape, whether its work 2K or 200K and not know anything about it except on how to point and steer it.

Ever noticed how the magazine and tv ads for 4wd's usually show the vehicles showering water and whatever all over the place.

But when a new owner tries to get his 4wd repaired under warranty the dealer may say that the vehicle was being used beyond what it was designed to do.

I read the 4WD monthly article and came to the conclusion that they chose the wrong vehicles.

They did this by setting an arbitary $80 budget figure.

This ensured that:

1. The high tech D3 HSE made the cut thus no need to take the coil sprung S model (less chance of gremlins).

2. The GU TD-6 (Manual) made the cut, thus no need to take the more popular and less sluggish 3.0Di Auto (Performance cost the GU points).

3. The Tojo 100 Sahara with the high tech suspension and extra gizmos missed the cut (more chance of gremlins).

IMHO, if I were a buyer, those vehicles would not have appeared together on a short list. If you were looking at a D3 DSE you would be comparing it to a Sahara and the TD-6 would probably not even be in the picture. If I were looking at a TD-6 the competition would be a different list altogether.

Just my 2 bits.

I had a 1996 RangeRover HSE 4.6 for 5 years. Lost year Boxing Day, I was driving along Alpine Way from Therabo on the way to Melbourne, all of a sudden , smoke coming out from dash board, I quickly parked on the side. Open the bonnet, frame was found at a spot underneath the brake fluid bottle, and the car was slowly brunt in gut. I lost my rangie and all my belongings in 30 mins. It was a total fire ban day as well. The fortunate thing was my family were OK it did not cause bush fire.

I am looking for a new 4WD now. it would be either a Prado or Patrol. Recently I make up my mind to go for a Patrol. Reasons are

(1) Much less electronic stuff than Prado or 100 series.
(2) Cheaper than 100 series.
(3) Patrol is still truck like and very much mechanical.
(4) Landrover's air suspension is great when it works. If it does not, it is hell !

When going to the bush, nothing is more important than reliability, comfort comes 2nd. By the way, I still have my old Merc for city driving.

Hi KKC

Much of the patrol's are still repairable and acessable by ordinary folks and apart from the massive performance a reason I choose a manual petrol one are that where it uses electronics it enhances reliability with things like indiviual top mounted coils 1200mm from ground and these drive spark plugs rated to over 100,000 kms and twin redundant Oxy sensors etc.
When it comes to servicing its all standard stuff, no fussy fuels and high pressure fuel pumps etc.

We returned from a West to East simpson trip a couple of weeks ago with 1 Rangie Sports, 2 D3's, 1 D2 and 1 D1.
The D3's absolutely ate up the soft sand but I probably wouldn't buy one for the reasons stated above - suspension lowering above 40kmh (not that this was a problem on the French line) but worst of all is the inability to lock the suspension when you want to change a flat tyre. You have to raise the vehicle to the full extent of it's travel (on a flimsy scissor jack - no hydraulic bottle jack supplied).
Nice cars but I'll stick with my D2 until they fix these issues with overrides.
