Thread: What happened to your D3/D4 today?

Later Ingenium 6 cyclinder may be better than the 4s though.

This report isn't very encouraging, to put it mildly:

Used Land Rover Discovery 5 review - ReDriven

..... the sheer number of reports of more sporadic mechanical, quality and electronic issues is honestly terrifying. It seems that every single element of the Disco [5] can and quite often does have some sort of issue attached to it.

Because of that, we’re sorry but it’s a no, you probably should not buy one, the very long list of potential issues, and the costs to repair them, are just too much risk.
.... as impressive as the Disco [5] is when it behaves, not only does it often rank at the bottom of its respective class, it’s proving to be arguably the very worst Land Rover or even Range Rover in general.


The earliest D5s are currently selling for about the same as the late model D4s, which tells its own story.

Not going to dispute any of that. In seeking and searching (and asking) I haven't been able to find any evidence that the Ingenium 6 diesel has had any issues such as all the others you have mentioned have. In use for barely 3 years at this point in time though.

Don't wash the engine bay Brad.

It's clean, and it still runs.

Just drove it…

583km Friday,
148km Saturday,
74km this morning
642km later today.

Love this vehicle….

Some manufacturers never seem to learn.....Newish Ingenium engines are a good example.

Sure some say it is to reduce oil wastage,even if the oil is recycled,but in the real world most of the vehicles are used in "Arduous" conditions,so need shorter drainage intervals,and due to the huge sump capacity will actually be wasting more oil than if the engine was designed for shorter drainage intervals.

Give away?

Nah,i am past crawling around vehicles,but maybe someone would be interested?

No. Its 100% compliance with life-long emissions and waste. They need to report a green vehicle.

Remember, the intent of a manufacturer is to sell product - first owner / warranty period is their only concern - beyond that they dont need to report how many resources the vehicle consumes.

They also very much cover the definition of Arduous use in the manual - that most wont read, or often wont be willing to pay for.

Who and where do they report a "green vehicle"to?

It is probably more to make the vehicle look cheaper to service,but as we know this comes back to bite them in the arse later on.

Many other manufacturers sell vehicles in the same markets with service intervals a lot shorter.

Lifelong emissions and waste reporting is very like how long is a piece of string,as there are so many variables.

I was recently reading about Euro7,seems they will be looking into rubber from tyres,plus a heap of additional factors with vehicle emissions.
Another huge headache for vehicle manufacturers.

Absolutely!
You are quite correct!
For the last 30 yrs of my working life prior retirement I was in the Earth Moving Industry with one of the world's largest manufacturers.
They increased their engine's sump capacities by roughly a 3rd, and extended the service intervals from 250hrs to 500 engine hrs.
The manufacturers also put huge pressure on the Oil companies to produce an engine oil which could "handle" the longer service intervals.

All for the sake of preaching to potential & existing customers that longer service intervals would:

1. fewer downtime hours due to less service time, therefore greater machine productivity.
2. better for the environment ('supposedly' less oil consumed)
3. reduced service costs (parts & labour)... even though the increased sump capacity caused higher oil cost.
etc.

We saw worse Oil Analysis results due to the longer hours on the oil.
Particularly, Chromium (cr) in piston rings, Iron (fe) in pistons, etc all see a rise in ppm (parts per million)

Also, it can be argued that by extending the oil hours, potential problems such as over-fueling (dribbling injectors, and the like) or presence of water in the oil (possible head gasket) takes longer for the problem to be noticed if you only take an oil analysis at time of oil change 500 hrs.

Because of this potential problem, we encouraged owners to continue taking an analysis every 250 hrs ie, between oil changes at 500 hrs.

But that in itself created a small problem, 'cos it's easy to hold the oil bottle under a draining spurt of oil via the sump plug, but not so easy to draw a sample into a bottle via a small hand held oil suction pump with tube down the dipstick tube or wherever.
Many owners wouldn't take the trouble to do it at that 250 hrs.

I religiously change my D4 oil/filter at 7-8,000 klms, and my MY2000 Hilux Diesel 3.0 4WD with 582,000 klms (engine never been touched) every 5,000 klms.
