** I've got the same problem as in the CED video. *** The difference between this issue and all other issues is the whistle noise at about 2000rpm - what/where is this noise? I've got a 2012 SD4 190. I've had the car for over 12 months and the problem never used to be there - it gradually appeared and got more frequent over time. I've had a JC tuning remap and replacement turbo (from breakers). Remap made no difference (this was when the problem wasn't so bad). Turbo replacement fixed the problem, but only for a few hundred miles and only when the car was warmed up - it got progressively worse so now it happens from startup. Changed MAF - no difference. Going to indy garage who fitted turbo to check hoses etc. My plan is to diagnose/swap out parts - cheapest ones first. Haldex has been serviced ok. Tyres are all the same. Note, this also happens in manual mode so probably not gear-change issue. |

Unfortunately there is no known cure, speaking from eight years of trying and getting so called experts involved . Dealers haven’t a clue . |

One thing I can add to this might be something to do with driving style. You will see from my list of FL2s below that we had a 2011 TD4 manual which was owned by my son and exhibited this problem and it really annoyed him. We had it back in the dealers a couple of times and they never sorted it despite getting LR involved. When he left the country to work in Africa I took over the car for several months until I traded it in and replaced it with my current 2014 SD4 auto. During the time that I had the 2011 model my wife and I never experienced the problem so what does that imply? 3 x FL1 2 manual + 1 auto

Hello Dorset, did you run that car in the winter months as a matter of interest, the fault only manifests its ugly head when the temp rises above 15c. |

Yes i thought about the temperature issue but I drove it regularly during warmer weather and took it for a ride a few times when my son was complaining about it but it just didn't happen for me. Incidentally, my LR dealer said that they had three other customers with the same issue but that sometimes people drive cars differently and that very often when they took them out for a test drive they didn't experience it either (or so they said). 3 x FL1 2 manual + 1 auto

Well now - there's a bit of a surprise! I had the car serviced a few weeks ago - local general repairs and service guys - but we do have a lot of landrovers in Wiltshire. This was a simple, minimal service as it had the waterpump yadayadayada job last year. Now, what with covid impact on life I've not been out much. Even had to resort to the battery charger. But.... today - it's 25C hot sunny dry - perfect weather for a cha cha. No cha cha! It drives like a normal car!!!! The service was just oil and filter, air filter, fuel filter, pollen filter, jet cleaner, screenwash and service interval reset. Nothing complicated.... Oil and pollen filter, screenwash seem unlikely candidates. Service reset - well unless their reset tool did other stuff I don't see that could be it...but??? Fuel filter, air filter and Jet cleaner seem most hopeful. Don't know if this helps anyone. |

Hi , don’t want to be a party pooper, but it will be back, been there , got the tee shirt. I was convinced it was fuel filter related as I didn’t have the problem until the minute the first new fuel filter was fitted. Today with 28 deg it is terrible. I’ve done all the usual so called cures without any progress. Good luck , and don’t try selling these annoying cars until mid winter. |

I've had this issue for several months. I got the turbo replaced (a 2nd hand one from breakers). It worked fine for a few hundred miles, but the problem came back gradually, then got progressively worse. The oil I used was from a distributor in the Midlands - the correct C1 classification, but the quality and compatibility with the 2.2 engine is unknown. The point is: I'm going to change the oil for Shell Helix Ultra...AF-L - the oil that is recommended for this engine (2.2 diesel with DPF). I will let you know if changing the oil for the expensive stuff (who knows what your local service centre uses?) improves it in any way. My local specialist who changed the turbo for me, said it is the gearbox, and didn't bother to change the oil to Shell Helix! I've bought the oil and will do it myself. In the long run, I think this is a relatively cheap way of eliminating a possible cause. I will also run the expensive diesel for a few tanks in case there has been any unwelcome buildups/blockages in the air path. Thanks. |

Note: I disconnected the MAF sensor connector which puts it in Reduced Performance mode and the problem disappears. However, this isn't a permanent solution.

MAF is reading the air introduced into the system. When disconnected, the system substitutes with a default value, based on RPM. You should ask yourself who is responsible for the quantity of air metered by the MAF... 1. Turbo 2. EGR You said the turbo has been changed. My money is on EGR. |

I tend to agree with you.

This is a brutal problem that seems to affect so many of us in the same way, with no fix, even after all the tests and replaced parts. Learned to drive in 2011.

Yes, I'm really p!ssed off because this is the first diesel car I've had in nearly 20 years, and I expected them to be reliable and plod on forever, but it turns out these engines are very temperamental.

As someone who spent his working life in the IT industry I would say that this is a pretty bold statement. The code in the ECU will no doubt be reading values from the map but what else is the ECU doing? and who created the new map ? etc
