Now that I know that the car was built for Germany and is now in Sweden, i might be able to shed some light. Your car was built to ISO standards, International Standards Organization. Cars sold in USA follow SAE, Society Of Automotive Engineers standards. OBDII was first required here in 1996, but some cars had them as early as 1994. The standard was known as J1850. Europe developed its own standard under ISO and called it ISO9141-2. In this system the modules only talked when asked and only to a scanner. they never talked to each other. Then around 1997 ISO14230 was introduced in Europe which was faster and had more interactive communication. Although these systems were developed to create standards, they still fell short and particularly in the area of scanners. A few years ago another system was developed in Europe called CAN or Controlled Area Network. It finally made it to our shores. There is someone who posts here and is a professional mechanic in Ireland, I believe. He is doing research on scanners now and could be a big help. I'll try to find his profile and post it.
