Got this noise and it's getting worse and worse..
Louder in 4th and 5th gear - 60 MPH +.
Quite hard to hear on the video unless you know the sound and listen out for it...
It comes on when you put your foot on the accelerator, and goes away completely when you lift off...
Had timing belt, all tensioners and water pump changed..
Tried running without alternator + A/C compressor belts on - still the noise remains
Any ideas anyone please
