Back with a couple new questions
https://www.audiworld.com/tech/wheel25.shtml
It for an A4 but was referrd to as being for a TT. Can I use this for my 2000 1.8TT?
Can a person do the brake system flush without having to go to Audi?
I saw MarTT's Alpine radio installation write-up. I thought these cars could not operate without the stock Bose system because of the close ECO and Instrument cluster integration - so I was wrong?
The bleeding/flushing can also be done without Audi. If you have a VAG/COM or similar you can do as thorough a job as they will.
For the radio you were wrong. You just lose the integration with the cluster. However, if you have a BOSE system, you cannot replace the speakers without replacing the amp.
Hope that helps!
No offense intended, but with some of your questions you might want to get some help along the way. Generally there are others that live close that are willing to help.
Someone has shown us all something. I am still learning.
