Rotors Size
 

Good day I've been looking around the forum and no luck, I was wondering how to find out if my Audi A6 95 has an AFC engine, I am trying to get the front and rear rotors for it and most places tell me some rotors would only fit AFC engine 12 Valve? But the engine I Know its 30 Valve its basically impossible for an A6 to be 12 valve? , so I'm a bit confused now I have the VIN number as WAUFA84A3SNXXXXXX
any help would be highly appreciated :o
