I'd tend to agree that someone there knows the truth behind this - that it was helped on its way. Certainly, with an auto 'box, you can't accidentally over-rev on up/down shifts, although in "Command Mode" I wonder if you can downshift to over-rev? I certainly use it when making progress because it gives better engine braking and throttle control.
In Command Shift, it won't downshift unless it is ready i.e. you can't over-rev. You can't 'block shift' on that gearbox either.M

I am wondering if someone hasn't been using it while Wetwipe was away and reset the mileage.
I think a Soovy s
t0gram (TM) is in order.
Wetwipe I have PMed you.
It'll be interesting to know what the mileage that's been logged on the Terrain Response ECU.I think a Soovy s
t0gram (TM) is in order.Wetwipe I have PMed you.
You can wind back the odo but can't do the TR ECU.
I linked this thread to the specialist i use to service and work on my car. He deals with D3/4s and RRS at work all day. Has repaired and replaced more than a few TDV6 engines inc buying a dead engined D3 and putting a new engine from a Jag S type in it, while swapping ancillaries to the D3 stuff.
This is his thinking on it.
2 theories about the Sport. I suspect when the car was serviced, the oil filter may not have been fitted correctly, causing damage to the bottom end, and is sheer coincidence it let go there and then.
Or, the orignal engine has failed, been replaced with an 08MY, and it is sheer coincidence it has failed there and then. Have only ever seen broken rods on an 08MY. Normally, it is a melted piston that causes the engines to die.
I've heard of cranks going but it's rare to happen, have only heard of it a couple of times on the Disco forum. Usually a duff injector kills a piston and then the engine. They are a strong engine, i know of one that did 478k before being removed. Plenty on the D3 site are sitting over 200k and a few nearing 300k with no issues bar routine servicing with correct oils and filters.
This shouldn't have failed, normal use wouldn't bring up this issue and the knocking would be clear for someone to switch off the engine to save it, so it's now down to finding how much abuse and where it took place.

Was pondering this last night (carefully) driving my 08 Disco3 home.One the Porsche bit of PH, there's often talk of an over-rev log in the engine management system. Woudl there be a similar 'event' log on the LR?

How do you over rev and auto? Usually caused by changing down to a gear not suitable for engine speed causing the engine to rev beyond the limiter. Not possible in an auto?

Thanks for all the comments chaps. All I can say about the damage is that I drove the car to the airport that morning with no problems. No warning lights, no noises, no hesitation, no oil patches on the garage floor etc.
Always started on the key, didn't drink oil and never missed a beat.
So, assuming the engine did let go in a freak way. What are the odds of that occurring in the 4 miles when being driven by the valet service?
Thing is, damage is so extensive it couldn't have continued to be driven. So, assuming the high odds above, how much higher that the engine grenaded just as it arrived on site?
To be fair to the Landy dealer they've not done a huge amount of diagnosis. It's clear from the 2.5 inch hole that the engine is trashed and they've concentrated in getting me mobile again.
Once the block is with the engineering co who supplied the replacement they will strip it, document, photograph & detail what went wrong. Naturally, I'll share the results!
As far as the repair goes, body is off, engine out, ancillaries swapped, new engine built, new belts, pulleys filters, turbo etc fitted and the new lump was going back in today. They hoped to start it on the key today but I've not been informed if this happened.

Any CCTV camera footage in the area.Always started on the key, didn't drink oil and never missed a beat.

Engines don't just grenade and loose oil without being used.

- the driver is a total and utter moron
- the throttle is floored in neutral (preferably straight from a cold start)
Or someone left your car running...
Happens, move car A to make space for car B .... get's called away, leaves it running... finally parks it up..turns it off.. too embarrassed to tell anyone it was making hell of a noise..
Stranger things have happened..
Years ago, I drove a Saab 9000 back from the south of France, doing a good speed on the motorway all through France and home, admittedly it froze that night, but came out in the morning and the exhaust manifold had cracked.. ran perfectly the day before, for over 1200 kms…
Cheers
