Discovery 3 Engine Management System Fault

Hello guys & gals, hoping you can help with my Discovery 3. It died suddenly on my whilst on my into work in Feb and I'm only just getting round to looking at it.

What happened:
Driving along no errors.
Engine system fault, within 30m car engine had died.
Ignition turns on, reports engine system fault.
Car turns over but does not start.

What I've tried so far:
Scanned with a standard OBD reader, nothing useful reported.
Removed battery, charged fully and reattached.
Bought a iCarsoft diagnostics tool and retrieved the follow errors (I'm hoping some are because it hasn't started since they say pending!):

A lot of that list looks like a major electrical failure. I wonder if the alternator has packed up? I think others have reported a similar, sudden stop like yours when the alternator has died. Previously:
2010 FL2 TD4e GS
‘93 Defender 110 200TDi CSW - still got this, non-runner on SORN.
‘87 Defender 90 4 cyl Petrol
‘83 110 CSW V8 - best ever!

Thanks Worms! That's interesting, I didn't think it would crank if the alternator had died?

These vehicles require plenty of volts. Check the battery voltage with nothing switched on, should be around 12.4 volts. Anything less, charge the battery first.

2005 Discovery 3 TDV6 Base 7 Seat Auto Java Black

Plus 1 with regards to the battery needing to be around 12.6 Vdc with the engine off

As you’ve taken details of the errors I would clear all of them, see if it will start , if not then rescan it to see what comes back

Also believe the U codes can normally be ignored , would u also be so kind to fill in ur profile please to let us know what engine , year etc D3 u have plse , many thks

Hope that also helps

I did replace the battery in June last year, so I guess it could be defective but feels unlikely. I've got a battery tester and multimeter, so I'll try and get out today to test it.

Profile now filled out, but for completeness here it's a Discovery 3 SE Tech with 2.7TD engine and automatic gearbox.

Camshaft sensor fault jumps out from that list.

Transfer case also reporting stuck clutch actuator, but I would not have thought that would cause a failure to start. 06 D3 SE / 15 LR D90 XS SW / 88 LR 90 Td5 / 68 BMW 2000 ti

As above, camshaft/timing belt failure. Check the front timing cover just to the upper left of the crank pulley for any sign of damage. Or better still remove it and check the condition of the belt, cams, and oil pump.

If the camshaft sensor developed a fault during engine operation the engine can continue to run as the PCM can compensate for this, but once the engine has stopped it cannot restart with a faulty sensor. yµ (idµ - eAµ) ψ=mψ

Managed to have a quick look.

Fresh charged battery, no change.

Got the radiator fan out, so take a good look at the timing cover (but didn't remove aux belt and pulleys). I couldn't see any damage, but took a picture for more seasoned eyes than mine.

Looks like it's the camshaft position sensor, unless there's anything else to try.

Much of the fault codes are likely to be a "cascade" usually caused by low voltage, and some may be historic.

Clear all of them and try two or three start attempts with a fully charged battery. Then read the codes again and post what comes back. It would be helpful if you could fill out your profile fully so we know exactly which model/type year vehicle we're dealing with.

Whoops, thought I had my profile filled out but I had missed the colour so it didn't show

sorted now.

Battery was only taken off charge at the weekend but I am going to put it on charge again tonight. In the mean time I've cleared the faults, some faults like ATCM wouldn't clear fully.

After trying to start 3 times, read the codes as follows:

Making progress, new camshaft sensor in hand. To quote Hayne's "Access is very limited".

In order to access the camshaft sensor I've done the following:
- Battery and battery tray removed
- Left hand EGR pipe removed
- EGR motor removed
- EGR cooler tipe coolant pipe removed
- Arch and arch liner removed for visibility/access

With that done I was able to get the old sensor out, nothing seems obviously wrong with it. But errors are errors at the moment.

However, when trying to refit the new one I've run into a problem. The Hayne's process says to use a mirror to look through the sensor window to see the back of the camshaft sprocket and rotate the crankshaft until a sprocket web is visible.
I was using a small inspection camera hooked up to my laptop, and when rotating the crankshaft I'm not seeing any movement at all.

Based on the diagrams, I'm expecting to see the camshaft pulley hub (part number 132436) rotating and coming past the window for each of it's three lobes.

This leaves me with a couple of options I think:
1) The inspection camera is pants and isn't clear (waiting on mirror to test)
2) The camshaft pulley isn't rotating either timing belt or camshaft failure

I'm rapidly heading to removing the timing cover for further inspection.[/quote]

Timing chain on that bank must have snapped or the timing belt itself. Remove the air intake pipes, rad cowl, fan, S/belt & tensioners, water pipes, crank pulley, and belt cover.

You can then examine the T/belt, if it's ok turn the crank and see if the cam is turning. yµ (idµ - eAµ) ψ=mψ
