My 2010 Q5 with 8k miles makes an annoying humming noise at 71-73mph, it started making it at about 6k miles. Because it was getting louder I took it to the dealer and they also noticed this noise, the mechanic said it was the first time he heard this kind of noise but didn't know what it was.

They kept my car for 10 days and replaced the rear differential.

When I picked up the car I asked if the noise was gone; the service advisor said: "No, the noise still there, we called Audi and they said that the noise may come from the exhaust system but they don't have a fix, they advise you to keep driving it until they find a fix...:

So I have my car back and still makes that horrible noise that is decreasing the pleasure of driving it.

Thanks a lot.

Oddly enough the uneven wear from not keeping up with the rotation may have been the cause. I changed the tires and bingo. It should be noted that these were 45 series tires. I would try rotating the tires first. If it changes anything then you know it's the tires. Good luck.

I traded a Murano for the Q5 and that suv made the same sound, when I took it to the dealer first, they replaced the transmission and the sound was still there, they ended up replacing the catalytic converter and now I don't recall if the sound disappeared. I took that as an excuse to get a new car - my beautiful Q5.

I was going to drive a brand new 2011 3.2 with the technician but I felt that was not going to be a good point of reference since it was a 2011 anyway. I'm adjusting to the sound now as everything else is nice in my car.
