2004 A6 2.7T Engine Squealing Noise after TB change 2 months ago.
Need some help on what this squealing noise might be after changing the TB and all the tensioners, rollers, and all the usual stuff. The TB Kit was from ECS Ultimate TB Kit with Gates. Did everything by the book and from some of the well written TB change DIYs on all of the Audi forum sites. After driving the car about a month this squealing noise appeared when the car is cold and started first in the morning and squeals for about 5-10 minutes then goes away for the rest of the drive. It needs to be sitting for hours before it comes back. Any ideas what this might be? I placed a couple of videos of the squealing sound problem. The first one is when the car is started in the morning and the second is when the squealing is just about gone after nearly 10 minutes later.
Thx in advance for any help!

It's kind of hard to say exactly what that could be. It is possible for one of your idlers or a tensioner to be defective and needs replacing already. It sucks, but it is certainly a possibility. This is what it sounds like to me.
Anyone else got any thoughts for the OP?

I don't believe the fan will turn on right away when the car is turned on unless the HVAC system is turned to LO on both sides and the blower motor's speed is turned to the max.
This certainly sounds like a bearing on an idler or tensioner going bad. Guess you got a bad batch?
