[V6-12v] Cold Stat Screetching, Grinding, Raspy Noise - Dealer Diagnosis Results

[Casimiro Izquierdo]

The dealer called me today to tell me that the noise is produced by the "secondary air pump".  As the service person explained it to me, there is an air pump bearing that goes bad and makes this horrible noise.  He ordered a new one and I should have the car ready by the end of the week.

I looked at the VAG diagnosis tool and have surmised that I probably need the one with CAN in order to be able to use it with a 2002 A6, a 1995 90S, and the possibility that I may buy a Jetta or Bug for my daughter next year.  I will have to build a computer for the garage - I do have enough parts to do that with comfortable processor resources.  The one thing that I don't like about the tool is the price.  At $349 it is not cheap - considering that the code tool for my 1999 BMW 740 cost only $149.00.

Any suggestions are appreciated and thank you for your help.
