2 weeks ago I had my crank pulley replaced because my was completely broken, since then I started noticing some light vibrations on the pedals and a very low “Uuuuuu” like noise when decelerating, could it be the pulley, my car is a 07 e91 330xd but I use it in rwd mode with XDelete, any other possible explanations, it’s a pretty low mileage and I’d say well kept car, I have around 90k miles, it’s a problem that is driving me crazy.
The pulley I installed is a Febi bilstein and I have replaced the belts.
Any help would be very appreciated.

might be a wheel bearing.

Wouldn’t I feel it in the steering wheel too?
And both the vibration and the sound would be present on acceleration too not only on deceleration.

Can you pop it into N to see if it’s engine rpm dependent?

Pull the belt and see if the sound goes away.
