Engine stopped - won't start - Looking for ideas

[Homestar]

I have a friend with a D3 - while driving down a hill today the engine stopped - It threw an error message - He isn't 100% sure of the wording as there was other stuff happening at the time - like pulling over safely - but he thinks it was something along the lines of 'Oxide' something 'System Error' - Vehicle will not start now. It is at a local Mechanic in the Country and they have no ideas about it.

To add to the above, he did hit some roadkill and has hosed the remains off under the guards and was wondering if something important lives in that area that may have got wet, but I'm not at all familiar with these vehicles but any thoughts or insight would as always be greatly appreciated.

If I get any more info I'll update it.

TIA - Gav.

Most mechanics these days have generic code readers such as the Snapon unit etc, so start with getting the engine codes read. That’s where the diagnosis should begin.

[Homestar]

let’s assume they don’t as the feedback was that they didn't know where to start - chances are the vehicle will be towed from where it is, but was hoping the snippet of the fault code may have jogged someone’s memory.

[BradC]

The errors that present on the dash are pretty generic and mostly useless. I'd start with "is it a TDV6 and does it still turn over without sounding like a bucket of bolts?"

Sounds like it's about to become "A Discovery in its natural habitat. A flat bed."

[Homestar]

Engine cranks fine but won't start - doesn't sound like it's done something internal and there were no noises when it stopped - he didn't even notice for a start as he was coasting down a hill and it was only at the bottom when he went for the accelerator again he noticed the dash lights etc and no running engine.

Country mechanic did have a fault code reader - the following info is what I've been given - I was sent a pic of the report but it has details on it I don't wish to share so below is the relevant info.

P0405 Exhaust Gas recirc
P1355 Refer official manual
P140A Refer official manual
P140D Refer official manual
P140E Refer official manual
P0494 Refer official manual
PO342 Refer official manual
P0046 Refer official manual
P0341 Camshaft position sensor

Does the cam position sensor fault shut the engine down - that's the one that stood out to me.

TIA

[Graeme]

It certainly would stop the engine.

[Homestar]

Thanks - that is what I would have assumed. Is the location awkward or easy to get to on the TDV6?

Does anyone know the part number off the top of their heads? I'll start Googling it.

[Graeme]

The camshaft belt and its tensioner need checking but hopefully only a sensor or sensor wiring fault. If the belt has broken or the tensioner attachment point has broken off then expect lots of bent valves.

How many kms since the camshaft belt was replaced?

[Homestar]

Thanks - not known re the timing belt or when it was done last - will check. Would have thought the mechanic would have noticed if it was broken or not but I'm also assuming it's behind a cover/s.

Camshaft sensor part number LR019287 - is that correct?

Cheers.

According to the Manuel it's item 9 :

From the WSM - fault code causes.

Realising that the D3 can generate lots of unrelated faults so this could just be a total coincidence - but at least 8 of the above fault codes can be caused by a short circuit to ground.

There are 4 EGR related faults, a Turbo boost control fault, a Viscous Fan fault, and two Crankshaft Position Sensor faults all which could be due to individual sensor failures or a short circuit to ground.

Ideally now you want to be able to clear all faults, then see which comes back first.

The crankshaft position sensor though should be the only fault in that list that stops the engine running.

[josh.huber]

Check the wiring schematic, they could be on a common power supply, one short can take down multiple circuits, giving you all those faults

[Graeme]

Check all the engine bay fuses and fusible links too.
The sensor earths are provided by the ecm so possibly a fault with one of the ecm earths.

[Tins]

Sorry to be old fashioned, but suck, squeeze, bang and blow was pretty easy to diagnose. It's when they want tinsel and tissue paper that it fails.

[shack]

I'd be thinking wiring issue / ECU failure as well.

Might be awkward to diagnose, had they recently been through water or a car wash?

[DiscoDB]

Graeme and shack raise good points.

May be worthwhile also pulling the transfer case module, and the engine ECU behind it and checking plugs for evidence of water or corrosion as well.

Water in this area has been known to generate lots of faults and prevent an engine starting. Worst case is the ECU has failed.

Here’s hoping it is something simple (like a bad earth).

[Homestar]

Haven’t had a chance to get an update today - will check later on but I think it was towed to LR.

[scarry]

I think it was towed to LR.

Better to go to a good Indie.....

Someone no doubt will tune in with one in the area.

[Homestar]

Was the closest place I think - there's no Indies down that way that would know LR's I don't think but there is an LR dealer. It's there now but they won't be looking at it for at least a week by the sounds of it.

[BradC]

The suspense is killing me.

Lol - so I am not the only one? [emoji6]🤣[emoji15]

[Homestar]

Well you’ll all have to wait a while! [emoji16]

[BradC]

I'm in WA, I'm used to it.

Any update Homestar?

[Tombie]

Especially if the answers going by rail

[DiscoDB]

Seems you weren’t kidding Homestar. Where was the car sent to - back to the UK? [emoji41]

[Sp1ney]

So.. Im the unhappy owner and thought I'd drop in to thank Homestar and the community here for their help and interest.
Long story short- Yes camshaft sensor had internal fault, but also when going to replace it, found Camshaft to be not rotating.

Investigation of the timing, found the timing belt tensioner had snapped, and left a hole in the engine block.
Strange all that violence made no noise.

New engine or new vehicle :(

[Eric SDV6SE]

Sorry to hear that. Territory 2.7 engine swap would be a good option.

[PerthDisco]

It’s not a hole in the block only a chunk of oil pump fell off. It’s a relatively silent and quick end one valves touch pistons.

Amazing still seeing this in 2022, 13 years after the part was updated.

[loanrangie]

Depending on when it went it may be repairable, mine went and was lucky to get away with only minor damage.

[DiscoDB]

Ouch - didn’t see that coming. Sorry to hear this.

As others have noted, do confirm it has done internal engine damage before committing to a new or replacement engine.

No noise when it stopped suddenly and being able to turn it over sounds hopeful. 🤞

Time to find a good Indy.

[DiscoJeffster]

Surely some bent valves and broken rockers. I’m sure there would have been interference when you’ve been trying to crank it to troubleshoot it.

Valves are vertical in the head and rarely get bent.
Rockers and cam caps/bolts take the brunt.

[Tombie]

Ouch.

Looks like it never had the updated pump. Wonder if it’s even had the timing belts done.
