List of VAG control modules, that will help you identify module based on its numeric code. Helpful when working with older diagnostic software.

Various computers in the car are called “Control Modules” or “Controllers”. (…) Your car will not have all the Control Modules listed in OBDeleven or VCDS, only the ones on the Applications Page for your car. Newer cars have more, older cars have fewer.
