As far as your A4 being more prone to breaking.....when you mod your car at all things get more prone to breaking. The old saying is fast-reliable-cheap.....pick 2. That being said I've ran for years on a stalled tranny with heads/cam with all the standard tranny tuning done. Tranny is still ticking.

<< A very happy Frost mail order tune customer.

Back to the OP's original question. Are you sure it is the air pump that you hear. Over top of the driver side wheel house there is a hose that runs along the fender. There should be a connector in that area, with the car running and the noise present, separate the connection. If the air pump is running you should feel a steady stream of air blowing out of the hose in your left hand (the one that runs to the front of the car).

Well none of the cars that I have had make this particular noise its like thecompression of something. Like a metal hum but its only during first gear of acceleration from a dead stop. If I gun it then its not there but if I push on the pedal gently you can hear the hum.

Yes true everything get pushed more. This is the car's second tranny in 9 years and I hardly drop the hammer on it.

Yea if frost contacts me I will talk more about it with him. I don't know how to install or remove a pcm.

I doubt it is the air pump. It may run for 2-3 minutes after cold startup. Check the hose as recommended since that will answer the question.
