I recently answered a post on another forum where I am a moderator concerning a poorly running 996 getting a CEL and codes indicating that it was running both overly rich and overly lean at the same time, which is obviously impossible, when scanned with a generic OBD II unit. When scanned with the Durametric it had a single missing cylinder and a bad coil pack. We also recently had a 986 in the shop that another shop had diagnosed as having a bad DME with a non Porsche specific, but quite expensive scanner; we found a aging O2 sensor.
Porsche uses a peculiar diagnostics software system that can often confuse other scan tools.
