from lookingat the faq AMK Date: 09/00 - 04/02 Emission: VVT, EU3 Throttle: drive-by-wire Injectors: big Turbo: K04 BAM Date: 08/01 - 05/02 Emission: VVT (check), EU3 Throttle: drive-by-wire Injectors: big Turbo: K04 Why do the dates overlap? Does this mean a later car can have the AMK 210bhp, than an an early 225? Im lookingat buying an s3 advertised as a 225,first registered 10/1/02. where on the car do i check the code? I have the cars chassis number, could audi tell me if its a 225 from that, without me having to contact the seller?
