Thread: Rhythmic loss of power under load - new common rail Defender

To Tim NZ.
Tim,
You mentioned a "manual". I have been unable to get hold of the new common rail manual so I have been making do with a TD5 manual. OK for everything but the engine and gearbox.... Can you let me know where you got yours.
Thanks.
Bill

Hi Bill

Bill, my comments might have been a bit ambiguous - the software upgrade didn't fix the rhythmic problem, just the very occasional regression into limp home mode and the strange noise when changing gears. Limited fuel flow would account for my experience, when I think about it. The problem only occurs when asking a lot of it. Back off the power a fraction and it can still get enough juice. Mine is a 110 cab chassis. It's led a fairly sheltered life - pushing it up Gap Hill would be as hard as it has worked. Suspect I would have the same problem towing a big load, but yet to find out. There is a hose that runs from the fuel filler back to the top of the tank. Not sure what it does, but I shortened both it and the main filler pipe to clear the rail under the tray. That had the effect of lowering it but shouldn't be a problem on an off-road vehicle designed to work at all angles.

Thanks again. The line to the top of the tank is the return fuel line - my understanding is that fuel runs through the common rail under very high pressure and what is not injected into the cylinders is returned to the tank through the return fuel line that runs parallel to the delivery line. Essentially the fuel runs in a continuous flow through the lines between the tank and the engine and back again (I think). I expect your vehicle would not have the problem that mine had - I actually broke down half way between Laverton and Warburton on the Great Central Road and through my lack of understanding of the common rail technology was stuck for two days and nights. I had been led to believe that you didn't have to bleed a common rail motor. Only when I purged the air from the system through pressurising the tank did I get going again. A truck driver who stopped to help us suggested this but I was wary at the time and didn't do it. Only when I had been towed 90km back to a roadhouse and talked to Alice Springs LR (great contact) did I do it and get underway again.

Thanks LR09WA. Mine is white 130 with white steel rims. The other one was a steel grey with alloy rimes - he has gone off somewhere. Thanks for the link to the manual. Are you in Maragret River?
