Heishman.com has a section called car talk. While it may be a hokey name, etc., their service department checks it on a regular basis and answers questions honestly, whether you take the car to them or to an independent. It is worth a visit and perhaps a posting of some questions that are unanswered. <p>Jon<br>'96 A4qs<ul><li><a href="http://www.heishman.com">Heishman Audi Web Site</a></li></ul>
