It only needs the failure of an oil seal on a turbo and the rest is history, a minor defect causing a major failure.

No Warranty unfortunately, myself and wife are so upset this has happened on the first day of a week away in Yorkshire.

Unfortunately it doesn't help with your vehicle Richard, but it could be useful to know whether or not your vehicle's secondary turbo drain is the later twin drain style. |

Very sorry to read this story. Is TDV8 the same as SDV8 or is the design different? I seem to recall that both TD & SD (albeit V6s) were available for the Discovery at one point. 2016 SDV8 AB |

ABAB, my understanding is that the engines are basically the same but 405 version set up for more power (perhaps because lighter car). I think the earliest 405s had the old style turbo drain (i.e. mod desirable), not sure when that was changed, maybe would have been by the time of the 2014 car here.

It is quite common on the TDV6 as fitted to the S-type Jag. The cause in this case is oil dilution with fuel due to failed DPF regens and the engine runs on the oil. I believe this was due to poor software handling of the DPF regen. Not heard of this cause on LR engines. I also know of someone who had this happen on a Pug. |

There were very high winds at the time whilst going up 25% gradient hill. Could this have been a factor? |

Does this very unfortunate event point to the turbo drain mod on all 4.4 TDV8's being more preventative than just dealing with the undesirable smoke when the second turbo cuts in, or have I misinterpreted the potential source of the oil entering the combustion cycle? |

This is sad news. It seems there is a club forming of owners with dead TDV8 Range Rovers |
