    this is work in progress for the TDV6 , apologises i can't comment on petrol engines as i haven't owned one

    accept no responsibility, i put this together in the hopes it may help , this is only a general guide from personally owning a D3 and from learning in what to look for . Choose carefully or they can become money pits , don’t buy the first one u see, if ur not sure simply walk away

    Please send me a pm if u see an error or would like something added,

    many thks
    Gary

    IMPORTANT QUESTIONS

    Make sure oil pump cover has been replaced to the new style, its a must , otherwise they can destroy the engine , particularly on 2007 onwards, it's been reported from other members that even MY2005 have failed, so always better to be on the safe safe and get them checked / replaced regardless of year

    Belts front and rear , tensioners , to be replaced every 105,000 miles or 7 x years , which ever comes first , the body does NOT have to be removed for the replacement of the belts

    Prices for a half decent base model ,are averaging 7 -8k , all depending on mileage, history condition etc

    as u go up the models , insurance becomes more expensive

    base model is ins group 33

    there are plenty of project D3 s on the market, but can work out very expensive to repair , buyer beware

    do an online full Hpi check
    MOT , check online for previous mots and adviseries
    https://www.gov.uk/check-mot-status

    service history
    any receipts , proof of parts and work done, ie , cam belts, oil pump cover , etc

    ENGINE

    cam belts to be replaced 105,000 miles or 7 years , if not allow £1,000 to replace( body does not need to come off for front and rear belts)
    look inside oil filler cap for any signs of water
    check all levels , brake servo is under the LH cover
    oil pump casing known to fail ( advisory to replace if it hasn't )

    if blanking egr valves, 2007 onwards req a software patch, ( please note new MOT May 2018 Regs )

    sticking turbo actuator arm
    look at general condition of battery , age or any signs of leakage
    condition of the engine bay, is there mud everywhere, signs of off roading
    remove oil filler cap , pull off plastic cover , look at hoses , wires , general condition

    ELECTRICAL / INTERIOR

    check everything works, with no bong sound warnings
    seats , windows, mirrors, etc
    press every switch
    depending on model , sat nav screen is clear with no flickering
    front or rear parking sensors work ok
    electronic hand brake known to stick, check operation
    when engine is started all warning lights go out , but ensure lights are there before hand
    with just the ign on check the srs airbag light shows up and goes out with the engine running
    2 x keys come with the purchase , they are conductive charging , so when the key is put into the ign it charges up the battery inside the keyfob , Ensure they work , replacement key approx £250

    BODY/ CHASSIS

    have a walk around, look at panels, doors, any cracking or chips
    see that panels line up, any overspray or previous damage
    check spare wheel
    look at entire chassis from front to back, oil leaks, wires damaged , dents in chassis etc,
    behind sill covers is an area that can rust
    look for any signs of leaks anywhere, i.e. front carpets , leaking sunroofs

    SUSPENSION

    compressors are renowned for failing
    whilst in the vehicle with the engine running , look at the instrument panel, there should be no symbols , whilst in normal mode, a symbol will appear in access and off road height

    suspension has 3 x levels , access , normal and off road height, check each height setting and that no warning messages come up in the display

    Wishbone bushes , to check these , grab the top of the wheel , pull the tyre towards u then away from u, in a rocking motion , trying to establish if there is any play in the bushes , to do it properly it needs to be jacked up, but this can at least give u a rough idea of the condition of the bushes

    important , check them in the access height setting.

    GEARBOX

    terrain response settings , go through each one

    snow
    mud
    sand
    rocks, display comes up saying to select low gear ,

    ensure smooth operation of hi /low transfer gearbox

    drive along slowly in each setting , listening out for noises or clunks

    centre diff lock is controlled electronically

    On the higher models, i.e. HSE some have a rear electronic diff lock ( eas an option )

    BRAKES

    look at all brake hoses and pipes
    back brake pipes can be an issue
    as mentioned , ensure electronic handbrake works correctly and doesn’t screech
    after a test drive check each wheel, are they hot , signs of sticking calliper , handbrake

    DRIVING

    on starting the engine, did it start straight away, any smoke , is the rev counter fluctuating a lot , is the engine smooth , look underneath for any fluids leaking

    find a quiet area with no other traffic, at around 5mph gently dab the brakes , listen out for any knocks, if u do can be an indication of worn wishbone bushes

    wishbone bushes are known to fail , the D3 is a heavy vehicle , 2.7 tons

    with ur hands just off the steering wheel, gently touch the brakes , does it pull to one side

    now back on the road at the relevant speed limit , it should be smooth and quiet , automatic gearbox changing without knocks or bangs , is kickdown smooth

    put ur foot down , does it pull ok, get it over 3,000 revs, are there any warning bongs or messages appear in the instrument panel , i.e. special programs off
    this can sometimes indicate a turbo or sticking turbo actuator arm issue, but not 100% until codes are read

    When parked up , CHECK the handbrake comes on without any screeching , if it does u may end up with a £1,000 bill if it reqs a new handbrake module

    KNOWN ISSUES

    compressor
    oil pump casing, make sure this has been replaced, if not get it done,
    turbo actuator arm sticking
    wishbone bushes
    rust under sill covers
    brake pedal switch
    suspension bushes, mainly front lower and rear upper
    eats brake pads, weighs 2.7 ton
    3 x electrical connectors that are behind front passengers inner wheel arch , known to cause errors


    DIAGNOSTICS

    can't recommend the Gap iid enough , is extremely beneficial , read and clear faults , calibrate suspension heights, able to update and flash engines ecu etc,

    http://www.gap-diagnostic.com/shop/iidtool-bt/

    will pay for its self very quickly, service is second to none from Gap

    currently £420 , bluetooth model better, can use with a phone or ipad

    GENERAL

    MPG - expect 20 -22 around town , 28-32 motorway
    very quiet at motorway speeds
    extremely comfortable and very nice to drive
    very capable on & off road
    plenty of room , 7x seats ( Early 2004 models can be 5 x seats and on coil suspension )
    they are complicated , so a diagnostic reader is a must

    as u go higher in the range the insurance becomes more expensive , Base model group 33

    COSTS

    compressor 450-500
    tyres 100-120 each
    cam belts, tensioner , allow a grand
    strut , around £200 each
    air tank £130

    to be continued
    always feel free if u think any of the information is wrong, sending me a pm plse, would rather know and correct it
    so that at the end of the day it's 100%

    hope this helps

    There's a petrol engine for the D3 as well. Why isn't that included in a buyers guide?

    Of course there is, but let's not make it even more difficult by including the petrol engine available in North America and Australia and just stay with the UK spec engine. :)

    hi mate

    glad the guide is of some useto to u , i just put it together from personnel experience

    the oil pump casing are just over £200 quid to buy , replaced it at the same time the belts and tensioners were also done

    don't take any notice if anyone says the body has to come off to replace the rear belt

    imagine u would have to allow a min of 3-400 quid to get the oil pump casing replaced

    allow a grand to get all the belts and tensioners done, inc water pump and oil pump casing

    hope that helps and plse ask away if u have any questions, always happy to help a fellow landy member

    as these are complicated landies you've got to go into it with open eyes, never buy on impulse , there are many good examples out there , alas there are also others that req a substantial amount of work and can easily turn into a huge money pit

    but at the end of the day they are awesome to drive, extremely comfortable, quiet at motorway speeds

    may i ask have u driven one yet

    Just spotted a 2006 with 100k fsh etc.

    Just asked him about belts and oil cover :)

    Seems good on paper but we'll see..... Towards Barnstaple is a long way to go for me so will be asking lots of questions :)

    hi

    hope the list i've done will be useful in what to look for, noticed there are some who take them as part exchange and wish to try and offload them to unsuspecting buyers

    if looked after they will easily do 250k

    also good to get a decent warranty

    alas i bought mine as a project , but if u can't turn spanners urself u have to factor the labour costs in

    glad it's of some use

    when i bought mine it was abit of a minefield , seeing how advanced the D3 is, i put this together from personal experience to help others in what to look for

    seems as D3 s become cheaper more are buying them, but of course there's always the money pits out there if they've not been looked after

    happy hunting and always happy to help where i can :)

    Do the replacement belts and tensioners come under servicing, ie should they be on the service history of an 8 year old D3 or this advice from experience?
