Just bought a 2007 A-4 Quattro and need some direction.

1) I am looking for a year specific service manual, any suggestions? All I have found cover several models and about 8 yrs.
2) would like to find a code reader tool ( ?? ) that will allow me to shut off such things as the service indicator
3) The wife got on the brakes hard the other day and the anti-lock brake light came on...any ideas why? and another reason why I need the code reader.

Thanks for the help
