Whinning noise acceleration/deceleration 318i e46 n46

[Venom]

Hi All,

Ive noticed recently that when I start engine from cold I can clearly hear a whining noise on acceleration and deceleration. It last until the engine is warmed up. Thought it might have been the cold weather not so sure now.

Last night took it out for a spin and it sounds louder than ever before.

Any ideas?

Chain or alternator.

I purchased the car approx 2 months ago, Dealership had to get a job done on the timing chain, cost them near 1800euro.

Its still under warranty. Is summit gonna give if I continue to drive it?

hard to tell, take a vid and lash it up here. Where exactly is the noise coming from?
