Diagnostic Procedures

From Ross-Tech Wiki

Car Info & Procedures

The following pages contain information about various car models, each page covering a generation such as Audi A3/S3 (8L) 1997 - 2003. In this case, Audi is the manufacturer, the model may be A3 or S3 and the chassis code in parentheses is 8L. This chassis code can be found in VIN digits 7&8. The year range shown is the model years, not the manufacture dates or registration dates.

On each page, you'll find a list of the possible diagnostics-capable control modules that can be found in each model. It's unlikely that a specific car will contain every possible control module so you should expect to be able to communicate with only those modules that are actually installed in your car, and only the ones that communicate with the factory scan tools. You'll also find information such as a photo to help identify the car's specific generation, a photo of the diagnostic port (DLC) location, and other pertinent details about the car as well. If a vehicle is not listed or if you have corrections or additions, please email us directly.
