Hi,
For three days on we have -20C here in Poland. I had no problem with starting up till today (-20 in the night, -14 in the morning). The engine engaged at the first time no problem, but after few seconds went down and died. I have tried few times more, drove 20 meters and again the same. There were no starange noises accompanying this. I have less than 10 liters of fuel in the fuel tank. Shall I suspect poor quality of fuel? Is it connected with low fuel level together with -20C? Or it is something else I should be worried? Best regards! Janusz www.yahodeville.com |

Hi Yaho, how low is the fuel? The engine management may be stopping you:
LOW FUEL INDICATION AND RUN DRY STRATEGY The run-dry strategy is used to maintain the systems fuel prime at fuel run out. It ensures the minimum amount of fuel is always left in the swirl pot. The instrument cluster activates the yellow low fuel warning light, (next to the fuel gauge) with 15% of fuel remaining in the tank. The fuel gauge will indicate empty with 11% of fuel left in the tank. With 4 liters left in the tank the run-dry strategy will be invoked. An engine mis-fire will be induced for approximately 1 mile after which the engine will be shut down. The engine can be re-started in mis-fire mode and will continue to run for a further mile until the engine shuts down again. This can be repeated until the fuel suction port in the tank is uncovered and causes engine fuel starvation and loss of prime. Re-starts after run-dry shut down are not recommended. Cheers, Tim |

Hi,
The fuel is the same as three days ago (-20C) but about the quality I am not sure (consistency of quality at fuel stations in Poland is an issue from time to time). The fuel lamp has activated yesterday evening, just after I have switched off the engine (I was waiting for somebody inside the car with electric systems on). According to manual it means 80km range, so c.a. 8 liters. One more thing - the "Check Engine" indicator. I think that it was "on" a second longer than it should, just after startup. Cheers!

I think TimmyNZ had got it well covered,I wonder if a fuel additive may help for extra anti waxing ? 2.4 90 XS

just a thought, doesn't alot of fuel in poland contain 30% bio-diesel.
bio-diesel isn't the best in cold temperatures - could this be the cause of the problem? TimmyNZ - how on earth do you know all that? what do you know about defenders running on 100% bio diesel during summer months? |

My initial thoughts were waxy fuel, only because it happened to me yesterday in a tractor, i parked it in the morning sun for an hour and it was OK.
AndrewS: could well be right in saying that it could be ice in the filter ? DEFENDER XS CSW 08 TONGA GREEN |

Hi,
Standard fuel in Poland (shall) contain onyl few % of bio additive. The fuel in my tank comes from cheap filling station Auchan (belongs to French supermarket). I have just heard that they get their fuel from the state reserves (it needs to be renewed from time to time - old one goes to Auchan). I will see tomorrow morning (today I will put better fuel). Forecast: -12C in the night. Janusz www.yahodeville.com |

Hi Caterham, that info is straight out of the workshop manual from Landrovers GTR website. http://www.landrovertechinfo.com/extlrprod/market.jsp (Of which you have to pay to use of course). From what Yaho has said in his last post it sounds like the fuel quality could be questionable. I'd be talking to the dealer about necessary precautions, additives, etc needed in the (very!) cold weather as the fuel is used to lubricate the HP fuel pump and the injectors. As for the bio diesel I understood the problem with using it in Common Rail Diesels like the Duratorque engine is that under extrem high pressures the bio can loose its lubrication properties, (especially if it isn't 100% clean), resulting in damage to the HP pump and the injectors. Cheers, Tim |
