I can't speak to the A6 directly, but both of my 90qs automatically test the
ABS after starting. I have never been certain whether it is at a fixed
time, or when you press on the brake within a certain time. On my car it is
very subtle, but on my wife's, built only a few VIN earlier, you would
believe that the brake pedal was scraping on the brake rotors.
Its not however. The vibration you feel is the ABS functioning; and when
you use it in an emergency, it will feel like this. Its best to be mentally
prepared for it. I suspect your A6 is just testing its brakes for you, just
as you should test your brakes when you start out at your convenience, not
at the convenience of an incipient accident.
