Does it change pitch with revs or with speed?

I will get a video on way home tonight. Personally I think it could be the torque converter starting to fail but I have no way of verifying this so I guess it will be a trip to a gearbox specialist.

That could even be the alternator? Maybe also check low range versus high range, see if that affects it. Perhaps also check some of the 4wd modes (grass/gravel/slow) to lock the diff and see if that has any affect... |

Could very well be signs of an impending alternator failure

Thanks for that link, it’s actually very similar to that noise!! Was hoping there was a root cause near the end of the thread but it seems you’re yet to fix this issue I agree it could be alternator on its way out too. I just don’t want to start replacing things to not fix the problem as it’s going to get very costly. I’m tempted to just leave it and see if it gets any worse. Although it is annoying!! |

I'm not sure of the location of the alternator but is it possible to get a long screwdriver pressed against the alternator and then press your ear on the handle and you should be able to hear if the alternator is noisy or not 2011 TDV8 Vogue SE |

I find the whining noise that increases with revs and speed is the the wife, solution is to remove wife and drive alone or drive very slowly keeping revs down.

Hmm, there's something, but I'm not sure I'd have noticed it if you'd not pointed it out, to be honest!

I think maybe I’m wanting a noise to be there and therefore hearing it more? Maybe it is just the normal cabin noise, I don’t know. I think I will wait and see if I notice any change in the noise before going any further, it is really quiet |

I started to hear a whining noise and ignored it for a while. As I started to think about it more I began monitoring the vehicle signals in the hidden menu, specifically the battery voltage reading which became more and more erratic and was nowhere near the voltage it should have been.

Hi Chris, thanks for info do you know if the hidden menu is accessible on 12MY? What steps do I need to take to access it?
