Yeah ... it is a bit mysterious. I do believe that if your car is older than so many years you're relegated to the test only places no matter what. When I needed a test to bring one of the V8s back to operating status the standard smog shop said I had to go to a test only place.
The techs can still run the pre-test ... I'm pretty sure the computer still transmits the results to Sacto ... the funny thing is that they still have to run a regular test even if the car passes the pretest ...
I don't know how many folks with older quattros get into the "catalytic converter preconditioning" mode where the engine has to run at 2500 RPM for 3 minutes ... the test only place I went to last actually did something similar by leaving the engine running at 2500 RPM for a minute before he plugged in the sniffer ... that way it passed the first time through ...
