Hi guys, having issues with my 07 pootrol, it's a 3.0 CRD that has has an EGR block, provent fitted, Dawes & needle fitted, welded inter cooler fitted, scanguage and butterfly removed. Generally runs great but now, for no apparent reason, just shuts down without any warning or fault codes showing. Mechanics in Euroa couldn't work it out, Nissan have looked at it, and have said that, even with the mods done to it, they are at a loss as to why it's shutting down. They reinstated the EGR, refitted the butterfly, removed the Dawes and needle valve and re plumbed the vac lines as factory and it still did the same thing, although Nissan agreed that it runs better with the mods. Reset the ECU both before and after the mods were removed and they are still at a loss as to what's causing it. ECU appears to be working fine. All wiring and connectors have been tested and found to be working properly.
Has anyone else had or heard of this happening before? And if so, what steps were taken to rectify it?
Will keep you all posted of any progress.
I had a similar problem with my old VL Commodore with the RB30 Nissan engine. Car would run fine but then cut out on me and not restart. Would leave it for a while and then it would come good again for a few hours or a day. Changed a few things on it as problem was intermittent. Eventually problem got worse and would not start at the mechanics (after getting towed). It was found to be the crank angle sensor. Replaced that and motor has worked fine ever since (19 years without it happening again).
I know the VL was petrol but the CRD also has a crank angle sensor as well as other electronic sensors so maybe one is playing up.
P.s. The problem started after I degreased the engine and sprayed water onto the engine (first efi car I had) which got into the electronics.
When the crank angle sensor went on mine it only went into lime mode. just backed off and it was fine.
It not the EMC relay if I got the term right. Its the one on the left in the picture, swap it with the aircon one to test.
Can you make it happen anytime you like ,?? If so how??

04 ST 3lt auto, not enough Mods to keep me happy, but getting there
There have been a couple of reports of Autos, with a faulty TPS Pedal, where they would hit the brake with the accelerator pressed and the engine would cut out ..... don't think this would be the case for you then, but you could try wiggling the TPS side to side whilst accelerating to see if anything happens, and check it for dust/dirt too.
Pump is fine.
It can shut down under acceleration, coasting and while on cruise, on the flat, down hill, up hill. Doesn't go into limp mode, just shuts down. At 100kph it won't even roll start. Give it 15 minutes or so and it will start again, then shut down once more. Could take a minute, could take an hour. Completely random.
We haven't yet swapped out the ECU as we didn't have one on hand at the time. Nissan doesn't think that the ECU is the problem but they aren't ruling it out. Tested the fuel and it came up clean, before and after the filter. Swapped out the filter, replaced the fuel lines. Swapped out injectors and glow plugs. Still the same. TPS working correctly. CAS has been swapped out. Cylinder compression across all 4 cylinders is within range. Nissan are scratching their heads.
