Hi Guys, So I'm finally moving up in the Audi 8L world as I'm test driving a '02 BAM S3 on Saturday. I currently have an AGU A3 so it is quite an upgrade. I have been searching all around for S3 buying guides to try and find common faults to look out for. I was wondering if people could add to the list or give be "tests" to do in order to make sure the car is as fault free as possible. I will be taking my VCDS lite cable to scan the car for fault codes. I'm hoping there are none.. Otherwise I will have to do my research to find out how serious they are. My biggest concern is the Quattro and Haldex. I will do some really tight turns at a very low speed to see if the back wheels feel like they are turning (ie the Haldex is stuck on). I also PM'd Tuffty and he advised that to test that the Haldex will kick in that you need to spin the front wheels to see if some power gets sent to the back. How much throttle will I need to give it in order to do that (in first)? It will be completely dry on Saturday, and I don't want the guy to think I'm just flogging his car. So basically I'm wondering, 1) Are there any other tests I can do to make sure the Haldex is operational aside from what I listed above? 2) It has a colour screen and a DVD player, are these units still prone to the volume issue where it is either incredible loud or quiet? 3) Any other things I should look out for that might not be too obvious. I've read through this thread http://www.audi-sport.net/xf/threads/audi-s3-buying-guide.101863/ but any issues highlighted in that thread seem like they would be very obvious and you would easily be able to tell something is wrong. So I'm looking for additional things that will cost quite a lot of money to fix, for example if I need to change the thermostat I'm not too worried. Thanks for the help guys and I'm very excited to (hopefully) be joining the S3 club!
