Hey bud, ease up. When I replied, there were no replies. I don't own an S80, but I do know there are diagnostic programs/tools you can get out there for other cars. My cousin has a VW GTI and he has something for his laptop that works like the dealer's tool that can be used to monitor the car, and reset codes etc. I've seen other shareware that allows limited monitoring from a Palm. I just don't know of one for Volvo (too bad). <P>I figured this board was for people to help others out. I didn't give any false information, I just gave the relative little I did know.<p>[This message has been edited by Evolvo (edited 10-17-2001).]
