The 2.2L Puma Defender,despite it's inherent issues is a very good drive provided the vehicle is set up properly.I must admit after looking at some of the post in the tread some things are un-acceptable.
The control strategy running the 2.2L Puma,like most on the market today run adaptive learning.This means over time the system adapts and compensates for drive behavior,engine loads,component wear and drift,etc.This type of strategy requires a specific set of entry conditions for start of life operation.Unfortunately this is not always done,hence the variation and this is why some of you will see it improve over time and some will see it remain the same or get worse,it is all down to initial set-up. Another point worth considering is the function of pilot injection,this aids in the start of the combustion process in a diesel reducing the shock loading of single shot injection and therefore reduces diesel knock.The controller for several reason turn off pilot injection and the root cause of your concern can be missed completely. What i will say is they are not all like that and if the complete first set-up is done correctly (complete set-up),not just pilot learn and no faults in the system you will see the difference. PS:Your system can have a concern and not generate a fault code Rgeards DieselYoda |

DieselYoda,
Thank you for the excellent explanation. Can you tell me if those start of life instructions are normally programmed in by Land Rover at the factory or by the supplying dealer? When I collected my vehicle I had to take it straight back to the dealer as it was speed restricted and wouldn't go above about 25mph. They told me it had been left in its PDI mode and left me drinking coffee for about 45 minutes while they, allegedly, sorted things out. I've always wondered exactly what they were up to, and have been suspicious that it's initial delivery checks were never actually carried out correctly. I'm to take it back to them early next week. I'd love to be able to tell them exactly what to do to sort this, especially since they either don't know, or don't care about, how to fix it. What's entailed in the complete set up, and can the dealer do this? With thanks, N. 2015 Defender 90 XS SW 1997 Defender 90 HT |

I have no doubt the 2.2 can be a good engine, I spent a half a day driving a land rover experience 2.2 110 before I bought mine. That 2.2 drove smoothly with loads of torque low down , that's why I bought one. Infortunately mine drives nothing like the land rover experience one. Obviously they could be bothered to make sure that one was sorted. I don't matter to land rover now I bought the vehicle and they don't care mine drives like its got a underpowered kankaroo under the bonnet. Never again, never. If you have a good one you are very lucky because there are lots of unhappy 2.2 drivers out there. |

Hi Rover, unhappy to the point where off loading was the only sane choice. A warranty is no use when JLR do not have dealerships or technicians who can help. Going back to a Series LR where the faults and issues are part of the experience and to be expected, whereas they are unacceptable on a list price of £32 k

ncow84,
When the vehicle is built there is a test sequence called EOL (END OF LINE TEST),this ensures the vehicle is to design intent as far as build spec,engine performance,ancillaries,etc.When this this test is done the vehicle system is placed in what is called delivery mode,sometimes called factory mode.One of the features of this mode is speed restriction which is removed by the selling dealer as part of the PDi process.The initial vehicle set-up i spoke about should be done at PDi,but there is an ongoing debate as to who should pay for it,hence the reason many are not done. Regards DieselYoda |

As it seems that you are getting nowhere with the supplying dealer and have some evidence that it was supplied to you without sufficient pre-delivery work then I think I would put the wheels in motion to reject it. At best/worst you'll get it fixed or worst/best get your money back.
The advice on this I've seen on other forums is to stop using the vehicle and - go in and talk, be nice and reasonable. - make no demands but state your position clearly with supporting facts. - don't get emotional. - have everything documented and written down prior to any negotiation. Rather than going in and trying to tell them how to fix it, I would just focus on getting the problem recognised and acknowledged. Ultimately it is up to them to satisfy you that it does not have a problem. Have their techs driven the vehicle with you? Have they supplied a different one for you to try to see if it has the same problem? It's true that there will be some variability between vehicles and I've noticed mine adapting and driving differently over time. If yours is really as bad as it sounds, then it should be very easy to prove with a back to back test with another vehicle. |

Many thanks, DieselYoda, exactly as I had suspected. Milesr3, they have not test driven it with me present, nor have they offered me a drive in another identical model, unfortunately for an A/B comparison to prove I have an issue the comparison vehicle would need to have been set up correctly, what are the chances of that?! They could take me out in another Defender that hasn't been set up properly and claim that it's completely normal. I can't imagine they'd ever admit to not having done this either. I explained to them on my last visit that I'd test driven another new vehicle on a business trip to England and that it drove completely differently to mine, that phased them not one bit. DieselYoda, if I took the vehicle to a third party (preferably a specialist with SDD) would they be able to read the ECU data and confirm that the set up has/not been done? 2015 Defender 90 XS SW 1997 Defender 90 HT |
