Yeah pretty much. The TSB says that the cause is "excessive noise burst signal during cranking on the camshaft position sensor circuit" so it must only be noise from the starter motor that upsets it.

Fingers crossed that this works ( or creditcard out , if it doesn't )
because you really don't want the labour charge that can go with
an electrical minefield !

Well I got some value out of my RACQ membership last night.... she wouldn't start again and I flattened the battery after trying to start it several times.
The RACQ guy connected the battery to his car and it still would do the same thing. Crank like crazy but never start. Occasionally it would cough as if it fired on 1 cylinder but then it would stop.
He eventually got it to start by spraying some Throttle Body and Carby cleaner into the Air Box.
It ran fine all the way home and has started again fine last night (stopped for petrol so it was still warm) and this morning (cold start).
Any ideas? I'm going to take it to my mechanic next week and see if there are any error codes of interest.

SubscriberThis is usually what happens when a cam sensor fails.
The crank sensor does not know which cylinder the engine stops on until it gets to the missing tooth.
The cam sensor tells the ECU which cylinder the engine is on immediately at crank.
If it fails the car can go perfectly once it has started as the crank sensor knows from the missing tooth once it it turning.

Thanks mate. I'll check that out and get the mechanic to check for error codes relating to the Cam Sensor.
I might try to find the Cam Sensor tonight and see if the connector is plugged in properly. I had a fault with the cruise control buttons not working and when I pulled the steering wheel off, the bloody plug wasn't joined together properly!

Hi,
My Disco 3 2005 Petrol 4.0 has started doing exactly what you discribe, driving my wife mad! Tell me, did you earth cable fix work?

Hi,
The earth strap didn't fix the issue but the cam sensor suggested by PhilipA turned out to be the issue.
The cam sensor is on the top of the engine and easy to get to if you pop the engine cover off. I removed mine by removing the bolt and disconnecting the connector. Gave it a clean (it had a film of oily crap on it) and refitted it and the problem went away. I can send you some more info if you need it.
Just another potential problem, and this happened to me a few years ago the Engine started to stall at lights while idling. It would run rough for a few seconds and then stop. I could stop it from stalling by applying a little bit of throttle. This turned out to be the MAP\EGR valve - D3 4.0 V6 Petrol - EGR valve \ MAP Sensor (aulro.com)

Hi again,
Ok, sounds like I need to clean the Cam Sensor. I looked on youtube, but can't find anything on it for the Disco 3 4.0. So, if you could send me more information, I would be very grateful.
Kind regards

Well this problem started to reappear again so I subscribed to LR Tech Info and downloaded LTB00335.
It mentions installing a new earth cable from one of the power steering pump bolts to the earth point behind the battery.
I bought 2m of 4AG cable and two large lugs. My cable ended up being 1.3m long but it could have been a tad shorter.
Firstly remove the engine cover (undo 4 nuts and temp remove the oil cap)
Disconnect and remove the battery, follow the negative lead to where it is bolted to the body. This is where one end of the new earth goes to.
Remove the top Power Steering Pump bolt. Refit the Power Steering Pump bolt with the cable attached.
Route the cable around the vacuum pipes and along the front of the battery box. From here I was able to squeeze the cable down the gap between the battery box and the body. Run the cable along side the fuse box and secure it to the bolt with the negative battery lead. I pulled the bonnet seal back a bit to get better access to the earth point. It looks difficult but LR have left just enough room for your hands to get in there.
LTB00335 specifically mentions that the new cable should be run as far away from the engine as possible.
So far the starting difficulties haven't reoccurred. I'll post back if they do. But heres hoping!
good I found this.. I am having the same problem of P 0335 code on my 2008 DIsco 3.. I got this car recently and the previous owner has been driving for 3 years with this error.. Now it , at times refuses to start, or starts and dies. I cleared the code and it appears again with the check engine lamp.. I like this to go away and going to follow your lead and install a negative cable.. Still I am lost as to how this new loop can solve the issue. The main negative cable is bolted not that far from the power steering pump .
Where did you get the original document from.????
Cheers mate..... Gamini Adelaide..
