I am now looking at the possibility that the computer I tried was in fact the wrong one. My computer has an Audi # ending with HA and the computer aht we tried has no letters at the end of the number but the number was the same. Also the Bosch number was different in the last 3 digits. I will get the exacxt numbers and post them.

Does anyone know of a reference where I can look up what these numbers signify?

Thanks again. You guys are really great.
