Found this while looking on the AoA site for service bulletins.<p><br> Where can I get parts to<br> improve the performance of<br> my Audi model?<br> Audi is not in a position to<br> recommend any type of<br> aftermarket performance<br> enhancer. Use of this type of<br> product may void your<br> warranty.<p><br>I still never found info on where to find out about service bulletins online. Anyone know where to find them?<p>The Link below:<br>http://www.audiusa.com/friends/feedback/faq.htm<p><ul><li><a href="http://www.audiusa.com/friends/feedback/faq.htm">AoA faq</a></li></ul>
