I’m not sure if this video picks it up well, but there is a noise on cold start up (worse the colder it is) to me it sounds like a pulley/bearing and I’m leaning towards the alternator.

battery is 66% charged and charging at I think 13.6v but can double check.

 

whats your thoughts please? 

 

Not sure on your engine but if it's the 3.0tdi it's known for timing chain issues.

Hey, for me it's sounds like alternator bearings (inside). It make sense why it's louder then it's colder. Your alternator works harder then battery is low (after cold start) and because of it makes this sound. Easiest way is to take off belt and turn every pulley/bearing and alternator by hand, most of the time you can hear it

Yer this was my thinking tbh. 
 

im suffering with man flu at the moment but this was my next plan, if I don’t hear it I’ll probably feel it direct through the bearing. 
 

although the alternators are a fortune 🤦‍♂️

Hi the alternators are not that much money unless you buy the Audi original part, I think they are made originally by Valeo or Denso but if you get the part number the world is your oyster, or just get your unit reconditioned.
