Chuckster, I am sorry to say that AFAIK, you are SOL unless you spend thousands. I remember seeing some info on a Volvo code reader made by the same company that makes the Volvo Scanner. It cost less than Volvo's, but still over a $1K. Too much in my book for a tree-shader. I bought a generic OBDII reader at Auto Zone for $180. It is not comprehensive by any means, but it does provide some info sometimes. Consider yourself lucky, the guys with cars that are on the VADIS system can't even add a CD player to their car without paying $$$ to the dealer who has to download a CD hack into their radio to recognize the CD changer. The VADIS costs an order of magnitude more than the Volvo Scan Tool (it is basically a Windows application) and requires a renewable License from Volvo (connects to Volvo servers during operation). How's that for a Big Brother? Let's face it, car manufacturers are out to take the service business out of the small guy's hands under the pretense of "progress". Same progress requires early S80s to be re-booted once in a while under normal operation. I have been in an S80 where the courtesy lights wouldn't go out when doors were shut and the owner had to turn the car off and restart it to fix the glitch. I remember Windoze 3.1 doing similar things. The trouble is owner has no recourse and is at the mercy of the car manufacturer to provide a software upgrade/patch.

Hopefully, this trend will reverse itself, but I doubt it. There is more money in upgrading your car's software than actually selling you the entire car, so the financial motivation is to keep doing what they are doing.

Best of luck to you and if you do find something for your PC that doesn't require a second mortgage on the house, please let us know. I know there are people (like myself) who are also very interested in this.

Cheers!
