Just died on the motorway, can’t work out why yet.
Just back home on the back of an AA truck and I am struggling to work out what’s wrong yet, not started stripping anything down as I am looking for any hints first.
Normal morning, done about 4 miles, as I went onto the motorway on slip felt some vibration, after a few hundred yards a clattering about like a belt flailing around then it cut out as I rolled onto the hard shoulder.
It would not even turn over after that, nothing when I pressed the start button, just ignition lights.
Once back in a safe place and a nosy under the bonnet, the belt and alternator look fine. There was no big bangs or anything metallic horrible sounding and still no interest in turning over.
The only fault codes from today are -
P0A1A 87 generator control module missing a message
P3041-3A camshaft position sensor
B1087-93 Lin bus A component failure
From the belt flapping like sound, wondering if it could be timing belt? I did replace about a year ago but didn’t do the rear fuel pump one, my thoughts on that was that it should not do any damage, just lose drive to the pump, doubt it would stop it turning over though.
Any suggestions would be great.
It’s a standard 3.0 SDV6. It has done 194k but still fit and towing well, until now!

Best of luck. Don’t think I’d be trying to start it with that sound.
Let alone a P3041…. my experience with that code isn’t the best.2015 LR4 HSE Lux Aintree Green

Sounds like T belt/chain or crank failure, only way to find out is to dive in and hope for the best.yµ (idµ - eAµ) ψ=mψ

Typical crank failure im afraid.

So finally got a wee look at it and took the fan off, big bar on the crank and slowly turned the engine over, all felt ok and with a finger in the oil filler, could feel the cams at that side rotating, so maybe the cam chain at the other side has broken?2010 XS with lots of upgrades

I'd look at a few other things before throwing the towel at the crank or timing chains even with the disconcerting cam sensor code.
Since you have been able to turn it over by hand you'd imagine the starter should also have no problem doing so! I wonder then if perhaps you have a major power failure (earth strap/battery/alternator) as pointed to by P0A1A 87 and B1087-93??
To test the earthing theory, and only if you are satisfied the timing belt is OK proceed as follows. Make sure the battery is fully charged 12.6v min) and connect a decent quality jump lead (or two of them) from the batt neg terminal/body to an exposed metal point on the engine. Then try a and see if it will turn over.
A broken HPFP belt would not prevent it from turning over and there should be a fault code (HPFP actuator stuck) or similar if it had snapped. The timing chain does not have any bearing the cam sensor as the pulses are generated from the rear of the cam belt pulley on the right hand bank (as you look into the engine)
So be certain the timing belt is sound before proceeding as the cam sensor code is still a concern. yµ (idµ - eAµ) ψ=mψ

Humm, interesting, and certainly worth a try. I am away with work just now but on that when I get back.
So timing belt certainty can really be gained by a few more full revolutions by hand hopefully?2010 XS with lots of upgrades

Ideally you'd want the front cover off if you want to be absolutely certain that there's nothing amiss with the belt or pulleys.
However, if you can turn over at least two revolutions by hand without any resistance besides compression, then you might reasonably conclude it's OK.
If it did suffer a failure when it died on the motorway some level of damage will very likely have been done then anyway, as the transmission may have continued to drive the engine until the car stopped!
Have faith, it's a Land Rover, what's the worst that can happen? yµ (idµ - eAµ) ψ=mψ
