Original D240 AdBlue injection timing fault from factory

Hi, First post here.
I've been looking to buy a Defender D240, and currently made an offer on a 2020 one that's had it's engine replaced at 40,000km (now got 80,000km).

Out of the approx 20 i've looked at so far, I've found two of these state they have had engine replaced. One at 40,000km and one at 70,000km.

One owner says: The D240 Engines (In a range of models) had a fault with the Ad blue injection timing. This was fixed in an update, but some damage was done to the engine prior to the update.

Other says: The original calibration of the 240D engine injected too much AdBlue and if they didn't update the calibration before 10,000km it results in damage.
(and this is a tech guy who runs a High Performance car business, so should be in the know)

Both were fixed under warranty, and calibration was updated.

Now I can't seem to find any info about this online, and it seems a major issue that some may not even know about ... !
Have i missed something searching the net (and this forum)?

That seems a bit strange as AdBlue is injected into the exhaust system, after the engine, in order to reduce NOx emissions. So problems in the AdBlue system shouldn't be damaging the engine.

You know, that was what i originally thought, but i was then thinking maybe i'm no expert, lol.

But i did read somewhere how the blocking of exhaust/DPF/CATconverter "type" stuff can damage the engine... but i have no idea what has happened here, only what they said (likely from the dealer).

So to be clear, they do not say injection INTO the engine...

And that may be why one said it can damage the engine after 10,000km if calibration was not updated, meaning possible build-up somewhere in the exhuast.

Stay away from the first 2.0 diesel four bangers. Go for a newer six
The 2.0 Petrol is fine and fast No Mud flaps for my 90.!

There were issues with oil dilution on the 2.0 lngenium, caused by incomplete DPF regeneration

Go for a 3.0 litre. No such issues with that engine. lt's a better unit as well, being a 3.0 litre six cylinder and more suited to the Defender.

Forget the D240 of derivatives of it. They have a habit of throwing timing chains and oil dilution issues. I managed to catch it before it went on my daughter’s Discovery Sport. My neighbour lost his engine because of it just out of warranty on his Evoke. Eiger Grey MY23 D250 SE with bits. Known as Noddy.

Land Rover stopped using the 2.0 liter in 2021 in the Defender.

The 3.0l six is a cracking engine.

The 3.0 I6 is proving reliable for me at least. Mine is an early 2021 70 reg, and was one of the very first 3.0 I6 diesel engines. Now on 29k and only engine related issues were recalls for exhaust bolts and auxiliary belt pulley.

I have seen a few posts around FB and the like saying there have been loads of failures of new Defenders, but I think they are just scaremongering. I’ve not heard of anyone with an I6 having a major failure requiring an engine swap.

Or am I wrong? 2021 Defender 110 X-Dynamic HSE D300 MHEV

I’ve got a late-2020 D200 3.0 litre on 86k miles and would agree it’s a great engine.

I’ve not heard of any catastrophic failures either. Mine has only needed a sensor in that time and regular servicing (every 10k miles).

Assume you are having a check on the carsales.com.au website ? I would agree with what is being said
in the thread, avoid the 2.0 4 cylinder diesels, especially if you are heading out into the wilds, go with the 6 cylinder in D250 or D300 format .. or if a Petrol floats your boat the P400 6 cylinder.. If you are on Facebook there are a couple of Australian New defender owners groups who can advise in terms of set
up for the Australian environment…. Cheers Jim yet another pommie bar steward down under

My wife wishes we were in Aus! She loves the heat. I'm in NZ, and not a lot of options here yet.
