Someone suggested that a noise from the intake on one of my threads:

My D3 had a similar issue which I put down to being ‘just how it is’
When I came to sell it, a fellow forum member came to look and said it ‘wasn’t right’ and picked up a ‘whooshing’ that I’d missed for two years; me, and a Land Rover mechanic / enthusiast
Turned out the previous owner hadn’t put the spindle back when they removed the butterfly valve when disabling the EGR valves. Left a permanent leak, and when the turbo was trying to up the air pressure, it just leaked and left an underpowered car.
Response was for the car to hesitate, downshift Then pull off
Putting the spindle in ..... different car!
Got a D4 when we emigrated, and similar issue with the air intake box not being properly located into the throttle-body
So, worth a look?
Good luck
Andy
