What is used to pull the codes off the our cars, what is the name of the device? Also, can you buy them through Audi and if so what is the part #? Is there a catalog that will list what codes mean what? and is there a copy of the parts application the dealers use, that will have a break down of the car and each part # that the parts computer has at the dealership?

THANKS!!!
