I am ringing the police tomorrow to get as much info as possible. I will also contact my broker for advice now you have said that. At the end of the day if the insurers don't like the sound of things they will simply counter claim from the dealers. I am told if that is done I will, after time get my £200 excess back and hopefully the £60 excess form my claim form he equipment stolen form my contents insurance.
On a more upbeat note, the dealers had a meeting with some people from land rover about why my lr keeps breaking down over the last year or so and they think they have come up with the cause. They think the pump is over pressurising and when the injectors reach critical pressure it is dumping fuel in leading to semi-hydrolock. Just waiting for parts to be delivered. Boy |

As an aside...
It amases me that all LR Dealers, no matter where in the world, all seem to be made from the same mould, filled with a lot of brown stuff and slime. Puma 110 - gone Series III 1973 - going strong |

A comment from "one_iota" has prompted me to inform you guys of my experience regarding loss of power and pressure sensor failure. Albeit not on the 2.4TDCi common rail diesel, but a common rail diesel none the less, which I assume all use similar engine software logic.
If the rail pressure sensor fails, the engine goes into a "limp home mode", which derates the engine (dumps fuel), resulting in loss of power. Because the injection system uses a constant displacement pump, the excess fuel has to go somewhere, and that's back to tank via the return fuel line. This fuel is now very hot and there's a lot of it. If the return line directs the fuel onto the tank walls or base it can melt a hole quite quickly in a polyethylene tank if not rectified straight away. So it's probably not a good idea to contiue driving with loss of power caused by a faulty pressure sensor. Bosun. |

I assume the fuel cooler would deal with that though? Mike |

Not sure, remember this is return fuel. Normally "excess" fuel would return to the tank via this route. I assume the cooler is for fuel going to the engine and not from it.

According to the manual the cooler is on the return line to the tank and not on the supply side. Mahn '08 Defender 110 ex '95 Disco 300 Tdi www.aulro.com |

This is correct. The cooler has to be on the return side to deal with arm fuel.
Its on the passenger side around the bulkhead on the chassis rail Mike |

Regarding the hot excess fuel issue returning to the tank.Could this possibly exit the tank through the breather pipe?I've recently extended mine up to the bulk head.The engine bay would not be the best place for hot fuel to be exiting the system!

Yesterday I've been to the dealer for my normal servicing,there were two Pumas there waiting for new engines due to this problem.What crossed my mind was the possibility this happening to me after the guarandee has expired and me being in the veeery sad position to pay for a new engine.
So trying to figure out some possible solutions to this problem I came out with the following: a)Dry the engine out of oil ,work it for some time and burn it,refill with old oil and claim for a new one (rather extreme solution). b)Install a webasto or other heater and use it every cold morning to heat the engine and therefore lower the viscosity of oil before startup . c)Put some good additive into the oil (SLICK,CERAMIZERetc.)so friction or heat during startup will not cause so much damage. Lets talk about this subject because I believe that many of us we will be in this very costly situation in the very near future. A very alarmed George NOT A TRANSIT |

I would think that if the vehicle was serviced as laid down in the handbook (especially by a maindealer) and there has been a history of engines giving bother with various faults caused by sensors and ECU related issues if a new engine was needed out of the warranty period I would think that provision has been made for this. I know LR might fight this but if there is a proven trail of substandard engines I would fight my case. If it went to court it would not be difficult to prove that a substantial number of units needed replacing. There is lots of stuff in print issued by LR as posted here to back up your case.I would also suggest that as LR gain more experience with this unit any problems that they find will be attended to in recalls to the dealer. It is not in LR's interest to have large numbers of engines packing up at the one time. In these times they want to sell vehicles so I do not think the scenario will arise. Enjoy your vehicle, and if the problem arises face it then. You could have the most perfect vehicle ever made yet write it off in an accident caused by someone else. Anyway if it's a bad design persay no doubt LR are chasing Ford for cost.
We all know that Ford dictated to LR to install this unit but if LR had had an engine of there own in development and near to completion surely Ford would have let them install it? They extra sales won by Ford by putting this unit in Defenders must be pretty small compared to the number of units installed in Transits. I am aware that LR did modifications to suit Defender applications which cost money. If a unit of their own was ready or nearly ready it would have been cheaper to use this. If the Td5 could have been readily modified to suit regulations this would have been ready to install. At the end of the day LR must have been fairly happy with the Puma to go down that route. We all love basic no nonsense designs but bureaucratic regulators have done away with this. I may be proven wrong down the line and would welcome further comment. My Puma is a family car and treated accordingly. Most others around here are farm vehicles and are highly thought of by their owners. One Transit owner was giving it it's first oil change at 36.000 miles and it is worked hard. So regular servicing with the book stamped should keep you right. 1982 88" 2.25 diesel 1992 110 200tdi csw -Zikali 2008 110 2.4 tdci csw-Zulu 2011 110 2.4 tdci csw-Masai |

Webasto is standard equipment on Defenders in Norway. I use mine every morning during the winter. It's running for half an hour before I start the engine. I've had problems with fuel rail twice........... Both times when shifting from 2nd to 3rd gear. But, after the last fuel rail installation, the engine sounds much more 'smooth'. 08MY Defender 2.4 SE |

Very interesting as our car still has the engine rattle that land rover australia have been chasing for the last 18months just like one iota's except he as only had it once ir twice we have also had ours go into limp mode 3 times and on occasions the rattle has happened twice not once with in the 500 meter distance from starting up. Landrover have just informed me that it was due to a blocked filter which i'm pretty sure when I cut it open that it wasn't blocked and i'm sure the second new filter that went on wasn't blocked either as the rattle never went away.. Can you let me know how you get on The Boy as at least you have people getting together and talking about yours we have to do our own research for the dealers over here YOU KNOW REHAB IS FOR QUITTERS!!!! |

Morning all
I dont have a knock at startup, but at 1800 rpm in every gear there is a knocking, it is definitely engine and not drivetrain, as it does it at same RPM in every gear. It is also bloody loud and not a slight engine knock, even the wife commented on it.......... I have also checked UJ's, props and hand brake housing to make sure, but nothing wrong there! Any one else experienced this problem? Cheers BB 2019 MY Disco 5 HSE Lux Audi A4 Avant 3.0L TDI Quattro - WOW 2016 90 Adventure |
