Hi Again,
Okay, for my second issue, it's an odd one.
2001 A6 2.7T Quattro Tiptronic
Problem: With HVAC on and fans blowing, if I step hard on the brakes, the fans (?) squeal like stuck pigs (yes, I know that is a funny statement coming from a guy in Iowa). It's as if gravity is pressing the fans against something that it shouldn't. I don't want to rip my dash apart to figure this out, and I can live with it, but if there's a simple solution, I'd love to hear it!

 

I would say a bad bearing in the blower motor. There is a writeup somewhere for oiling the motor.

Best of luck,

Jeff
