Check to see if it's the air con, by pressing ECON when you'll hear it again. |

Do you get this in gear and in neutral? At that low speed you could run it on a ramp? (Please don't think I am suggesting you do this as that would be against H&S law I would imagine ) I understand that a garage did this to my car, without my knowledge of course, to identify a wheelbearing issue. |

Thanks for the suggestions, I will check the air con tomorrow, but think it is coming from the driveline. It's more of a grornch grornch type of noise, difficult to describe in words, so I made one up that sounds like it! It's like a brake pad being stuck on a warped disc, but these have been checked and found to be okay.

Yes I saw yours was an auto, you can Rev it in neutral while stood still. Worth checking? |

Thanks RichP, will give it a try. Looking at everything to trace the noise. Even the garage who are a landnrover specialist are stumped. 2013 SD4 Auto HSE Luxury Firenze Red

Was your replacement diff new? Landy has now gone. |

Reconditioned diff with upgraded bearings on the crown pinion, so I don't think it is that. 2013 SD4 Auto HSE Luxury Firenze Red

That was a thought Snappa, but doesn't a wheel bearing normally get louder the faster you go? This noise seems to only be noticeable at low speed off the throttle, say under 20 mph, when coasting. 2013 SD4 Auto HSE Luxury Firenze Red

Did you tried the ECON, when you hear the noise, like I've said?

Tried that Alex, whilst you can hear the air con compressor engage, it makes no noise over than changing the engine note slightly under load. Also tried reving the engine in neutral, no joy.

By way of an update, had the car back to the specialist today to get them to track down the whirring noise. Diagnosed a failed bearing on the propshaft above the DPF.

I find it a disgrace that the thing that this vehicle is all about ie it's 4 wheel drive system, seems to be the most problematic part of this otherwise excellent vehicle. Thanks to FoMoCo for your design input and use of underrated components . I hope that lessons have been learned for later LR vehicles. 3 x FL1 2 manual + 1 auto
