Howdy, I have the exact same problem. Did you work out what the problem was in your case please.

 

Remove the fan, disassemble it and clean it good internally, with electric contact cleaner , scuff pads, reassemble, hit with 12v on bench and it should work, worked for me fans still going a year later and saved me 300 bucks on buying a fan.

 

THANK YOU!! This just happened to my 2009 Q7 at 162k miles. I never would have thought about trying to rehab/clean the fan, but I gave it a shot and it wasn't a bad job at all. I encourage others to do this. It's surprisingly easy to get to - just six T20 screws to remove the glove box, unsnap the cover in the passenger footwell and disconnect the light, and you have full access to all the screws and wiring to remove the fan.
