Hello to everyone! A friend owned me money and since he can't pay up we made a trade and thats how I got this Audi S3 in mint condition. It has an OCT tuning Chip, OZ lightweight rims and a sport exhaust declared at 291HP but until I place it on a dyno I don't believe anyone. I've been driving Peugeot for the past 30 years and I have two of them, a classic 505 and a 206 and the latter will have to go since three cars are too much. Here is a quick reference manual for Audi S3 http://www.1-na-1.com/audi/S3.pdf My problem is that my S3 has a Cassette player which is outdated and I want to change it with an original CD player but I don't have the official User Manual. At the Audi representative in Belgrade, they can't get me the one I need. Can anyone tell me what I need to look for?
