Audi A4 Cabriolet: I have a 2004 A4 cab with 40k miles. Recently

This answer was rated:

I have a 2004 A4 cab with 40k miles. Recently started to make a faint whining noise with acceleration only -- sounds like a race car so my kids love it. Doesn't occur when car is in neutral and I rev engine. Hasn't affected performance; accelerates fine and no change in mpg. Any thoughts?

I haven't resolved my issue yet. Any thoughts on what could be causing the above-detailed, slight "whining" noise? Sounds a little bit like the sound a race car may make. Only occurs during acceleration. No change in auto performance, and no warning lights have ever come on.
I know this model has has some transmission issues. Is this sound consistent with an incipient transmission problem?
Normally a trans noise concern will be there only in certain gears if its a internal pressure concern. If its the differential then it will be there all the time and at all speeds. Other things to check are the wheel bearings and the tire wear surface. If you can get the car on a rack, then run it in gear to see if it occurs while off the ground so you can listen from underneath the car.
