First things first. I searched the archives with no luck. I don't know if this bothers anyone else, but it would be great to have the air-recycle button work at all tempetures and not just when the A/C is on. Have you ever followed a 1985 mercedes-benz diesel with high miles? The exhaust is lethal. Does anyone know if the button can be tweaked with codes in anyway? Thanks.<br>Brian 97 1.8TQM

The following link will show you how it works. It cannot work if the temperature is already below freezing, though.<p>What I do is switch it on in my heated garage before driving to work. The windows fog up, but a small price to pay for protection from carbon monoxide.<p>Good Luck!<p>(and thanks to the person who originally discovered it, wherever he may be!)<p>--<br>Adil<br>'97 A4 2.8 QMS<ul><li><a href="http://www.pinkpank.net/a4org/971113/messages/71.shtml">Recirc, half an answer (LONG)</a></li></ul>
