LR3 / LR4 buying guide and maintenance tips

I pulled this list from another Facebook group which is mostly European. There is a lot of good information here but some of it is geared toward the Diesel motor. Apparently the 4.4 V8 is pretty solid so there isn't a whole lot of info out there I can find. Please let me know how can update this list to include or maybe categorize the diesel recommendations from the gas motor recommendations.

Some of this list may also work for the LR4 as well so that distinction may need to be made as well.

What to look for when buying a D3, and what are the common faults / things to consider. Here are the most common:

1) HSE is the 'top' model with most options fitted as standard.

2) Buy on condition rather than age or mileage.

3) Evidence of service history / money being spent is vital - these vehicles require preventative maintenance. A good 'tell tale' for a vehicle run on a shoestring budget is to look at the tyres. Are they a reputable make and good tread left? Good sign. Big stack of invoices? Good sign.

4) These are heavy vehicles - suspension components, bushes, and wheel bearings wear out, as do differentials and prop-shaft centre bearings.

5) Brakes take a hammering too. Check the disks and pads for excessive wear.

6) The EGR valves generally fail in time. They can be replaced, and there are other cheaper solutions available that cannot be officially sanctioned.

7) The suspension compressor is a weak point. Make sure the suspension raises and lowers efficiently, with no noises, and no error messages on the dashboard. Ideally, it will have been replaced by the uprated AMK version.

8) Battery and alternator usually need replacing at about 8 years old. A common sign that the battery is getting weak is the message "special programs not available" appearing temporarily after starting up.

9) Cambelt and fuel pump belt need changing at 7 years / 105K miles. The body does *not* need to come off to replace the belts.

10) Changing the oil pump at the same time as the belts is advisable. There have been instances of the lug that holds the tensioner snapping off and wrecking engines, and the redesigned pump appears to be much strengthened.

11) Getting the gearbox oil changed / flushed is advisable at around 80K miles.

12) Check the MOT history (online) on any vehicle you are thinking of buying - it will tell you a lot.

13) The electronic parking brake can fail, and it's expensive when it does. There is an emergency release accessible from inside the cabin.

14) A warranty is a good idea if you can stretch to it. Lots are available, and it's worth asking for experiences of members of this group.

15) an IID Tool is worth buying to do your own diagnostic work. Other tools can do similar jobs, including iCarsoft i930, but doesn't offer as many features.

16) A remote FBH controller is worth its weight in gold to those that have them. The FBH is a 'fuel burning heater' and kicks in below 5 Celsius to warm the engine faster on cold days. It is the thing that smells and smokes from the front left of the D3 and always worries people in the winter. A remote control turns it into a useful parking heater.

17) There was a recall on the detachable tow bar. Take it to Land Rover to get it checked out. There was also a recall regarding a vacuum pipe (top left of the engine standing at the front looking to the rear of the D3) - if you don't have a strange looking 'loop' arrangement, get it checked out by Land Rover.

18) The locking wheel bolts sometimes sheer off - replace them with standard ones. The supplied wheel brace is considered inadequate for removing the bolts if they have ever been tightened with an air wrench. Get a proper one prior to actually needing it!

19) Sometimes the central locking plays up, due to a crummy connection on the passenger side under the plastic sill. It can be soldered up for a permanent fix.

20) The cable that releases the rear tailgate sometimes breaks, as does the microswitch in the handle - awkward to repair when it goes. Symptoms are the tailgate not opening and / or a clicking noise but not opening.

21) Shudder or surging in the acceleration at about 2,000 rpm usually means the torque converter is failing - an oil flush or Dr Tranny can give it a bit more life.

22) There were some instances of crank bearings spinning and wrecking engines. If that happens to you, go talk to Land Rover, as they had a programme to deal with this, depending on conditions being met. As far as it known, there is no way to repair engines with spun crank bearings.

23) The turbo actuator can stick causing very poor acceleration at slow speeds. Easy enough to free up, if fiddly.

24) The MAP sensor has a tendency to clog up. Easy to remove and clean, and there is a modified part with a larger port available that is less prone to clogging.

25) The long intercooler pipe has a tendency to split near the top of the engine compartment on the left as you stand in front of the engine, causing almost total loss of performance, and loads of smoke. Easy DIY to replace, and should possibly be considered preventative maintenance once over about 7 or 8 years of age.

26) There are usually one or two D3's for sale by members of this group. They won't be the cheapest available, but they are likely to be amonst the most 'honest' with declared issues.

27) Road tax is cheaper on older D3's - that said, don't let this put you off newer models - the difference isn't large enough to use it as a buying decision.

28) Fuel economy is between 22 and 32 MPG depending on usage. These are not 'green' vehicles - and that's not why you're buying it!

29) Don't let just any old mechanic work on your D3. These are specialised machines and you need to know what you're doing if you want to minimise the costs - rather than just throwing parts at it. Take it to a recognised specialist and save yourself a lot of grief.

30) The centre console Fridge was thought to be standard on HSE's in 2007 but not necessarily present in 2008 onwards. They can be retrofitted :)

31) The crossover pipe that links one bank of cylinders to the turbo on the other side of the engine can fail - most usually due to the centre bracket not being refitted after work on the gearbox causing vibration and cracking. It can be replaced without taking the body off, but it is very awkward, and the pipe itself is expensive.

32) The fuel injectors can't be serviced, and they're roughly £200 each just for the part - keep in mind you have 6 of them! It's worth using good fuel and / or using injector cleaner every now and then to keep them in good shape.

33) The glow plugs can fail - symptom being difficult starting, smoke on starting, or rough running for a while after starting. You might not notice until 3 of the 6 have failed. They have a tendency to snap on removal, needing the heads to be taken off. A workaround is to fit a remote FBH controller and pre-heat the engine prior to starting.

34) The black plastic trim does fade. Several people swear by using smooth peanut butter to restore the colour.

35) The elements in the heated windscreen are fragile and can be broken by stone chips. There is no way to repair them once broken, other than a windscreen replacement.

36) The winch mechanism to lower the spare wheel sometimes jams up. Make it part of your routine to test it / loosen it from time to time. Don't wait until you need it before discovering that it is seized up.

37) Some people who have needed replacement engines have successfully fitted the 2.7 diesel engine out of a Jaguar. This is obviously a risky proposition as it is unclear just how much of the internals are different / similar or modified for Land Rover versus Jaguar.

Despite all of the above, almost all of us love our D3's and wouldn't want anything else. Don't have nightmares, do sleep well :)

Great list, you are right that some things do not apply to NAS vehicles, but regardless all good info. (I NEED TO MENTION HERE THAT SOME INFORMATION MAY BE INCORRECT AND I WILL RECTIFY THE POSTINGS IF SOMETHING COMES UP) (NOT RESPONSIBLE FOR MISUSE ETC ETC)

For our vehicles (mostly V8's) I would add:

>Service records are KING (NAS vehicles were more expensive luxury models with more things that break so maintenance history should be 99% complete for your wallet's safety). My advice is to drop price immediately if there is not a complete history of the vehicle, or walk away. Carfax is a horrible indicator of a previous life.

>These vehicles are excellent in all regards, and if treated correctly will serve you for years to come. The easiest way if you do not care about all the technical stuff, or in general want a fool-proof method of getting a good Discovery 3/4 is to take it to a decent Land Rover dealership and get it inspected. It is not super expensive and gives you an excellent picture of the status of the vehicle to start with.

And some specific service stuff...: (4.4L AJV8)

>Differentials do go bad, more people need to be changing diff fluids around 30k intervals. T-case should have been serviced by 75k at the very least. This keeps them a lot happier.

>Transmissions (we have autos) should be flushed at or around 75k, ZF recommends this, even if LR insists to keep unit sealed until 150k. They have to make their money somehow...

>Throttle body will get dirty along with MAF, this is a common place to clean if you experience rough idling behavior. Be careful with the MAF when cleaning, they have been known to break from cleaning attempts.

>Water leaks (ingress) will destroy electronics and make repairs insanely difficult/expensive. The two problem areas are sunroof drains, and a windshield cowl that will cup right above the HVAC intake port on passenger side. Replace every few years and use sealant (or install an extended shield for HVAC under the cowl) to prevent future ingress). Drains for sunroof typically block at A pillars and can be snaked out carefully or blown out with air once the tube ends are located and trimmed (older trucks had a very bad tube ending design that failed closed).

>Absolutely correct the standard lug wrench is garbage for how high most tire shops/mechanics torque those lugnuts on. Best practice is to carry a good 15" or 18" breaker bar AND a hilift jack (the handle you can use as a perfect cheater bar) or other extension bar. Owners literally cannot change their tires sometimes because of how tight the lugnuts have gone on. The chrome capped lugnuts can have water enter between the steel and the chrome cap, causing swelling. While the nuts are supposed to work with a 22mm socket, we often have to resort to 7/8 SAE for older nuts that have lived in humid climates. A good-quality torque wrench is ideal to carry and use on these.

>If planning to work on your vehicle AT ALL, get an IID tool. Insane amount of functionality, good manual, great customer service from Patrick at GAP. It will pay for itself in short order.

>The locking diff models can be identified either by looking up the VIN, or by the presence of a full size spare on NAS trucks. On standard models only the center diff locks so you can look at the 4x4 screen to make sure.

>The cooling system is complex, the bleeder valve on top of the engine is unfortunately super fragile and will shatter if you look at it wrong. Replace with brass or OEM (every few years), and keep a spare. DexCool is the coolant of choice. Working on the thing is another matter entirely.

>Thermostats have been known to fail as the rubber gasket will separate from the t-stat. It can be replaced with some difficulty.

>FOR FLUSHING/BLEEDING AIR FROM COOLING SYSTEM: Navydevildoc and Bbyer (among others) posted about this process elsewhere, so this is loosely adapted from their directions and those provided by a tech at my local dealer.

Keep the bleed valve at top of engine closed. Just don't bother. Keep your bleed screw on expansion tank closed. Remove expansion tank cap (the big round one) and leave it off. Start the engine and warm it up. After a bit once it has warmed up a little, keep the engine revved at 3000rpm for a few minutes. What you are doing is trying to get the engine temp up and the thermostat to open up and flush the whole loop through. Once this happens, fluid levels in the coolant tank will drop a bit, shut the engine down and let cool for a little while. Then repeat. And once more (3rd time) if you want to be super careful. Keep an eye on coolant levels but you really only add coolant if you just flushed the system. This should get all the bubbles out. (Atlantic British has a video explaining this process). Basically, heat, open T-stat, watch coolant levels, let cool, add coolant as needed. Your coolant return section of the expansion tank is where the little hose brings coolant back through a section of the tank so you can physically watch the bubbles as they come through.

This is best done with a GAP tool so you can watch the exact temps of the engine, and look at fan speed, engine rpm, and coolant/oil temps to get a good picture of what is going on. Bbyer (on other forums) has mentioned that the temp gauge is unreliable on the truck if there is air in the system because it is supposed to register coolant not air temp. IIRC the thermostat opens up around 197F. I have used on a chevy truck having someone else stand at the engine with a hand on the hose coming out of the t-stat housing and he would yell when he felt coolant/heat coming through, just in case you weren't watching temps.

>Coolant is DexCool, so dealers carry LR official XLC concentrated stuff. Prestone 50/50 premixed DexCool is a good alternative too and can be had at local stores for cheap. Pretty good stuff. Honestly anything with a decent brand label that says DexCool should be okay.

>EPB (electronic parking brake) can fail, either the switch itself or the module. Try fixing switch first ($50 vs module-$3000), sometimes it has a bad connection. If the brake fails engaged you can tell by either smoking rear brakes, or by removing the wheels and looking at the hub. There is a plastic screw that melts from heat. If intact, you are okay.

>the fan requires specialty tools (some have avoided this by using rental kits from autozone or other, which I think absolutely SUCK, since most wrenches are designed for Ford 4-bolt pulleys and not the Jag 3-bolt pulleys), and can be found for decent prices from Assenmacher in CO. Belts are actually really easy to do once you get the fan off, it is recommended that you change the idler pulley at that time since you are already there and it is not that expensive as opposed to a failure on the road later.

>Oil changes should include replacing the drain pan plug every other change (extreme worst case-will strip threads). A lot of guys have now moved to using bigger size filters (K&N and others) for better flow/filtration, and they don't leak like some OEM ones. Castrol EDGE (formerly syntec) 5w-30 is the good stuff and you can get 5 quart jugs at walmart for ~$40-50. I am aware that newer trucks have weird oil specs so follow whatever your truck says.

>compressors on old trucks were Hitachis and are less superior than AMK, which is desired as mentioned above. The drier unit can degrade over time and send little particulate matter from the dessicant beads into the air lines which cause leaks, usually at the valve blocks or strut fittings.

>The airbox has a small rubber drain valve that rots away and will compromise the integrity of your intake air. Seal up or install a better drain, especially if fording water or going in mud a lot. Take out your airbox sometime and see how/where it pulls air from the outside, sometimes it can take some fiddling to get the intake cleaner but it is a pretty good design as stock.

>Unfortunately the air suspension can and will move on its own at various times during day/night/when you are under the vehicle/having issues on the road. It has been discussed that switches can be wired to depower certain fuses to prevent this during either maintenance or arduous conditions where the suspension moving would cause problems (wading/fording/rock crawling). The master fuse (to disconnect ONLY in emergencies/maintenance) is F26E (20A) (engine bay box), and the secondary ("safe" to use on move-be careful) is F35P (5A) (glove box). A lot of the groundwork for this was done by Land Rover DIY legend ;) Bruce Byer (Bbyer), so thanks Bruce! A write up will be forthcoming at some point.

1) HSE is the 'top' model with most options fitted as standard.

Actually the HSE LUX is the "top" model. The main difference with the LUX is the upgraded leather it comes with, which is far superior to the standard leather. Things like Xenon HID projections lights and the upgraded HK sound system were also a part of the LUX package, however I believe both of these were also available options on non-LUXs where as the upgraded leather was only available to the LUX.

A superb list, just a pointer on number 12.

In the UK, IIRC the DVLA website for online MOT's has only the most recent up to 3 years mot history, I only know this as I recently checked out a D2 at work with 100k on it.

And number 2, many buyers are gearing towards mainly LR main dealer servicing & maintenance and prepared to pay for that premium.

Unsure of other European specific requirements/criteria.

Overall, certainly a invaluable list.

Thanks for updating this list! Let me know how to make this a sticky if that is something I do on my end.

>>Rear Climate Control Models (HSE Only I think) - For cooling system issues/service this makes things much more complicated. The rear system needs to be bled separately from the front (so I was told). I had the thermostat replaced, thermostat housing, bleed valve and coolant flush by a Non-Dealer LR Specialist for $550

For those that have the NAS version we have North America LR3/LR4 facebook group for photos and fun. (link in signature)

This is a great list. Not just for buying a LR3/4 but for maintaining your own. I have to say I've learned a few things.

This is an awesome list and I tend to be rather overboard about maintenance of my LR4, but I think it's very important.

Please feel to correct any glaring errors in what I added. This is only what I know so far. All stuff is pretty commonly asked in the tech sections of forums.

I think to make it a sticky either PM a forum Moderator direct or wait to see if they pick up on the suggestion, I'm on a few forums & each have they're own etiquette.

I'm glad I found this list, I'm currently researching a vehicle for off-road adventures and I'm in love with the LR3 or LR4 but now I'm a little scared too when I hear an electronic brake module costing $3000. That's insane, what is wrong with a cable like most cars have?
Other things that worry me are "suspension compressor is a weak point", "Changing the oil pump" and other things on the list.

I'm currently driving an 04 Chevy Trailblazer (5.3L V8) with 168K miles and the only thing not working are my dash gauges but there's quite a few places on the web that will replace all stepper motors for a little over $100. I have replaced brake rotors and regular 3K oil changes and the beast is running beautifully.
Before the Trailblazer I drove a Explorer Sport Trac and it did 177K miles without a single engine or transmission problem. Before the Explorer I drove a GMC Jimmy to 170K miles and the only thing that failed was a window motor and a fuel pump.

I really want to buy a LR3 or 4, going to read much more on this forum but please help me make the decision :coffee:

I drool over some of the pictures I have seen on the picture thread :drool:

George-
Keep in mind the internet is biased toward issues; nobody posts up 'nothing's wrong with my truck, it just works' on the scale that folks post up issues to get sorted. The good news about the LR3/LR4 platform is that it is significantly more reliable and robust than previous generations of Rovers-and keep in mind how many of them are still out on the road.

The level of complexity (and ability) of a Rover is hard to understate, that many moving parts does at times mean issues, that said the forums are also illustrative that most issues are known and depending on skill with a wrench a lot of $$$ can be saved by doing work yourself. Reliability is as much a facet of being able to repair something when necessary as it is the false hope that nothing will ever go wrong if its being used as intended.

I'd also highlight that things like the compressor being weak point may not be a fair characterization (and this is coming from a guy who switched to coils for other reasons). Given the amount of work the EAS has to do, and considering that most Hitachi units are now at 10 years of doing that work, it isn't unreasonable to see them needing a rebuild or a replacement. Likewise other things are as much a facet of maintenance vice poor design; take care of the truck and it will take care of you. Though it may get expensive at times.

Hence the advice of finding the best maintained, with records, vehicle possible and have a reserve of cash b/c a rover may well test you after purchase to see if you really want to own her.

Having these trucks is a relationship, not a commodity. At least that's been my mostly love, sometimes hate, experience with them.

I have and will continue to question the $3000 figure for the hand brake, it's a £330 part to buy, there is no way it costs £1200 to fit it. That's bull**** on so many levels it would make a politician embarrassed.

The hand brake should be stripped, cleaned and adjusted at every service. It's in the book and the reason so many fail is due to them not being serviced and set up properly so they go out of adjustment, screech when applied and fault out. Not the cars fault it's owner doesn't maintain it properly.

Bear in mind the D3/LR3 is a very complex car. When i scan it with my IID tool. It goes through 19 ecu's for checking systems. That's a lot of ecu's.
Plus sensors, etc. Plus it weighs 2.7 tons. Which is very heavy. I know in the US there are bigger and heavier, but in the UK, it's one of the heaviest cars on sale.

They can and are a love hate relationship of a car.
Mine is good, but it can throw up the odd hiccup.

UPDATE!

Speaking of possible maintenance ideas(mods feel free to move if this is an inappropriate place), I noticed a unique sound two times today. The only two times I drove and turned off the truck, immediately after turning off the engine I continued to hear a low volume noise. Sounded like a small motor running, or possibly a fan. It seemed to be coming from the passenger side, and it only lasts for 10-20 seconds and stops. Both instances were after a 15 minute, 5-6 mile commute. Any ideas or direction on what I should be checking for with this? Odo is currently at 121xxx and Im in the process of scheduling my 120k inspection.

Thank you!

Ashamed to admit this, but I figured out what the stupid noise was. The damn console refrigerator... Guess when I let my boy play in the truck the other day when I was installing the Polymax, he must've cut it on. Oh well, just glad it wasn't something more serious!
