Well I've done about 150 miles so far today and "played" with it when accelerating on the motorway etc. Mine definately seems to be most noticeable from about 50mph. I did stick the window down to hear the fait whoosh, but all I could hear was the loud whoosh of the wind wizzing past. 
I'll try and see if I get the same issues at 30mph as well. I have also noticed that I get the same thing with cruise control on and if I use command shift, although I have only changed gear when the car would have done in auto anyway.
Where is £10forcash based? I wonder if it might be worth getting my gearbox reset. How much did that cost? D3 HSE MY05 Auto

10forcash is based in Derby although he travels around. PM him for a price to reset your gearbox. TBH, I don't think its a permanent fix, because it will soon learn bad habits again.

I have a similar thing on my car.
What I discovered that it is temperature depended, when I get out in the morning and temp is below around 8C, I get "rev hunting" (goes up couple of hundred revs, goes down, goes up, etc) at usualy 30mph steady speed, at night going home I am getting out an underground parking and the car is around 20C and I do not get "rev hunting". It is much rearer during summer time. I was thinking maybe it depends on the gearbox oil temp. LR D3 S Black, Auto TDV6

Ok an update!
I was driving down the M4 today, having been driving for some time so car was well up to temp it had been doing it's usual surging from time to time - I generally notice it above 50 mph. Suddenly the car start to vibrate very badly, so much so that I thought I had a puncture. I slowed to get onto the hard shoulder when I dropped below about 40 it eased off. After a minute or so it seemed ok and continued to be ok as I increased speed up to normal speed.
It is still doing it's normal surging and mild vibration.
Any ideas? I feel that if I take it to the dealers I am not going to get anywhere, it will probably cost me loads for them to try things out and I'll be without the D3 for ages. D3 HSE MY05 Auto

Stu, that sounds just like the park brake is binding. If it happens again, check the rear disks for smoke/flames etc.

Hi,
I had the same thing again today, and it did feel at though the car was being held back, eventually it stopped suddenly and the car surged forward, in much the same way that it does when the gas is applied and the EBP is on. I did look for signs of smoke etc but there ewas none and after I stopped (about 30 mins later) I checked the temp of the discs, but they seemed quite hot, but not more than they would be normally - although I'm not expert and don't often feel my brakes!
If it is the EPB binding, do you know if I can remove a fuse, or do something else to disable it to test the theory, obviously I still need to be able to drive so it's no good removing the fuse if the car won't start etc.
Thanks

I've experienced the binding epb a few times, and each time it was when I had used the 'drive away' release feature that the auto has.
If you manually release the epb before you drive away, it might help. I can't give you any logic behind my theory, its just from experience. I remember well being stood on the shoulder of the M56 with smoke pouring out of the right rear wheel arch  I stopped expecting to see a shredded tyre.

I'll try and do some comparisons, but generally I haven't been bothering the the EPB, although when I have, I have used the drive away function rather than disengaging it. I'll experiment, but it would be good to know if I can disable it as well. Thanks for the info, how is yours going? D3 HSE MY05 Auto

I'm not driving it this week, I have been using the Punto for work, trying to keep the miles of it as much as possible.

After 235000Km my disco 3 motor still hunts
In auto "normal & in "sports" as will as in fixed gear position
Seems to hunt more when under load - first acceleration (not quick) and when progressing up hill (even a low gradient)
Always accompanied by a "whooshing" (whoosh – whoosh it can go on for some time if you do not change the accelerator position) - sound such as, that it seems to be an air leak - as if a flexible hose is collapsing with vacuum (negative pressure) once collapsed (open) the pressure differential equals & the "fault" "closes" and the sequence recommences
There is a power surge which even passengers feel
A college with a bmw had a similar problem; after 18mths bwm found a pipe "melted" on to part of the turbo - changing this removed the fault ...... perhaps
My own Land garage is perhaps a little like my colleagues but it is now + 48mths.
I also have the dead to stalling – but it picks up – this is only occasionally
I also have experienced the juddering that is mentioned – usually when passing through a roundabout when commencing to accelerate again only occasionally.
I have a hand brake problem (I do not use it now) when put on lots of grinding screeching noise & then you have to try several times to release it
Would enjoy reading some positive answers to these problems

A bit more info.
I was away at the weekend and I now have a terrible noise coming from the rear passenger side wheel. It sounds at though I have a load of tin cans rattling about - although much louder.
I am now thinking that I have 2 issues:
1 - The revs surging up and down and
2 - The noise from the rear wheel - which I think might have caused the violent vibration I felt the other day.
Anyway I have booked it into Guy Salmon in Portsmouth on Thursday so we'll see what they find.
If anyone has any ideas on the noise I'd be grateful to know what you think. D3 HSE MY05 Auto

Well I have an update.
I took the car to Guy Salmon in Portsmouth.
They found out that the terrible noise is due to the rear passenger side brake having "broken up" so they have sorted that out, which is good.
The rev surging issue is a different matter though, they have determined to be due to a gear slipping in the automatic gear box. They say that it needs a whole new gear box!
So it looks like I might have bought a pup.
Does anyone know my legal rights? I bought the car over the phone without seeing it so I think I have more rights?
