Hello guys.I 'm looking for the software that Audi uses to check car's "brain". Any idea about it's name or a place that i can downloaded? By the way i just buy an A3 1.8 2003 model. I'm thinking to place to it an s3 look. Any ideas about the parts that i need? Thanks!

 

VAG, rosstech.com

 

Ok with the program but i also want you to tell me the exact type of cable that i need to connect the car with the laptop. Aaa!!!!!!and where i can find some updates for my car's software. I also have an A4 1.6 1999 so i will need for both. Thanks again!
