The OBD II scanner review site was founded by B. Wiley. The OBD scanner that I used when I had my 2002 Audi S4 bi-turbo was invaluable. When I added the MTM chip and exhaust I was getting some error codes. I used the OBD II scanner to clear codes when sending the car into dealer for regular scheduled maintenance. I hope you enjoy the reviews listed in the site.
