Good Evening!
I have a 2015 Audi S1 and under heavy/full acceleration I get a rotational sounding high pitch 'ch-ch-ch' noise that increases with road speed. The noise is ONLY present under acceleration with Quattro enabled.
As soon as I pull the fuse on the Haldex, the sound disappears.
- clutch was changed a few months ago and the propshaft/transfer box/gearbox were removed. Since this the noise has been present.
Video in the link below shows the noise with Quattro enabled and the noise gone with the Haldex fuse pulled (in FWD mode).

Can anyone help?
Don't think it's anything rubbing on the propshaft etc as i've had a good look and can't see anything.
thanks
