Wanted to give a brief write up of a friends current Disco woe, and see if there was any advice on what he should be doing next.
He's on a 60 plate SDV6 which has just tipped over 126k miles.
Prior to the current issues, he had owned the car for circa 8 months, and had on a couple of occasions had the "Restricted Performance" error show on the dash. On returning to the garage he bought from, they had reset fault, but not given an specific diagnosis - working theory is that this is not directly related to the following.
Car was MoT'd a couple weeks ago, and he'd also noticed the car was due to have main belts changed. Garage doing the test centre would not do this, and referred him to a specialist, where he booked in for the following week for service / belt changes.
A couple of days later he noticed an unusual noise while driving, and pulled over to check the car at a retail park - only to find there was no oil visible on the dipstick.
No low oil warning had ever triggered on the dash / diagnostics system.
He went and found some oil, topped up and took the car home - the following morning the oil he had put in was all over his drive.
Car was put on a trailer by AA and taken to the garage who was booked to do the service / belt change.
The garage re-filled the car, and identified the oil pump as the main source of the oil leak.
They replaced the oil pump, and crankshaft oil seal, then did the belt change & service leaving him with a £1500 bill.
However the car has also been returned with a report saying:
"Once car back up and running, road tested and checked: No Leak.
Engine does have a harshness to it and the bottom end of the engine sounds to be knocking when revved and engine is warm. This is due to the engine previously running with very little / no oil in it"
To follow that up, they verbally gave him an advisory that the engine is likely to have only a couple of weeks of life left in it, and recommended a Spares or Repair sale of the car, or an Engine replacement which they quoted c.£7k for.
So my questions for the community are:
Does anyone see any potential links between "Restricted Performance" errors the sales garage had dismissed and the Oil Pump failure?
Does it seem reasonable to people that the 'specialist' service garage went ahead with £1500 of work on the car before coming back with a diagnosis that the engine wasn't viable before they took it in?
Any thoughts on what could cause the engine to empty itself of oil without tripping a single warning?
Is it worth the cost of going ahead with the engine replacement?
Are there any recommendations out there between the New engine (c.£7k) option, and a reconditioned unit (c.£5k fitted)
Could there be other causes of the "Restricted Performance" error which would not be addressed by an engine change?
Any thoughts would be very much appreciated I'm sure. He's considering moving to an FL2, or a Disco Sport, but I know his heart is still in the D4.2005 Discovery 3 HSE Auto

The car's system should have alerted the driver that the oil level is low, if it was low enough to damage the engine.
Also they shoul not have done any work to it unless authorized by the owner to go ahead with it.

But, did the dipstick say not available, so he thought no oil, topped it up which was then overfilled which caused some sort of damage?
I assume he knew how to check the dipstick correctly?
Just reread the post which said he had noise then checked to find no oil!
Who was the specialist? Surely a specialist would know what it should sound like and would question the issue first before replacing belts??

Well that was one of my questions, but they seem to have done the originally booked work without doing those checks first.
And yeah, oil all dash sensored in the D4 (every day a school day), but there were no driver warnings.
If over filling was the problem, I'd have thought only issue would be the broken oil pump rather than all the bottom end damage being reported.
It's a whole heap of mess for sure.2005 Discovery 3 HSE Auto

Low oil level will not trigger a warning, only no oil pressure.... by then its usually too late.

I thought there was a "Oil Level Critically Low" or similar?
Surely that's not related to oil pressure is it?

Restricted performance can be one of many different things. Did your friend overfill the engine, which has caused the pump problem. You say the oil was on the drive, but had it been leaking while he was still driving it? I would have thought there should have been an oil critical level warning.
The garage question is a dodgy one. They were asked to change the belts which they did, but should they have fired up the engine after changing the oil pump first? It's quite likely the job was done in one hit then the engine was started, and at that point they discovered the engine fault. I wouldn't like to argue that one in a court of law!

No that's oil level , but you'd only see it IF you check the on screen monitor, same as checking on a dip stick.
But once drivng, the warning light is for oil pressure, or lack of and hence Steve's comment about being too late Altox GSM FBH controller thread

Just had another thought, some of the early D4s had the 2.7V6, in which case it would have a dipstick, which might explain the lack of a dash warning. Not to sure if they had a low oil warning, or just an oil pressure light.
