Weird cooing noise

Hi folks

This is my first post, so please be gentle...

Bought a 2004 Freelander TD4 Sport about a month back and have noticed a strange cooing noise when driving at certain speeds. It's sometimes noticeable around 50mph but far more audible driving between 70 & 80mph. It sounds a bit like Vic & Bob trying to coax down the Dove from Above with the gift of the coo.

I think I've attached a zipped mp3 of the sound it makes (recorded on my phone), you can hear the cooing around the 9-14 second mark and again towards the end (24s).

Any ideas?
TIA

Haven't listened to the noise as im on my phone and it won't open, but could this be the "strangled duck" noise connected to the EGR blanking mod???? Just a thought.

i think the gaylander has been used as pigeon shed in the past...

Thanks for the suggestion Mick. Not sure how it could be confused with a duck sound though, it's more of a dove or pigeon sound. Have you managed to listen to the sound?

Or has anyone else?

Is it MPH or RPM related?

Turbo? If you accelerate hard when it's cold and clutch to change you can get a noise similar to that described.

Wouldn't have thought so.
The EGR noise happens when the engine is shutting down but Blunt says this happens when travelling at speed. Completely unrelated I would say.

My guess is mph... as it makes the noise when accelerating and with foot off the accelerator.

That is a strange one, quite prominent about 10 seconds into the recording. It sounds like some sort of resonance as the rpm seems stable.
Sorry never noticed anything like it before, the only thing is to try to pinpoint by ear.

Edit.......Might be early sign of VCU bearing failure??

Sounds... expensive

£300 drive-in drive out - what mileage is the Freelander

55000ish

Shouldn't be the VCU - that's usually 80k
