If I had been stopped in the Mercedes I have the EGR disconnected and they would have seen that.

Its strictly voluntary, you can refuse. They are doing it to test the smog check stations which are notorious for cheating, not the owners of the cars. There is not pass/fail here for you. I was stopped at one of those in Sacramento in my 190e. I told the officer that I don't have time and drove away.

4.3: Inspection Protocol
Currently, AQR teams use the following test procedure. Using the random sample method, a
CHP officer selects vehicles and directs them into the test lane as soon as the test of the previous
vehicle is complete. The greeter explains to the driver that the test is part of a survey to evaluate
the Smog Check Program and that there are no penalties, emissions-related or otherwise,
associated with the test. The BAR greeter also provides the driver with a consumer information
handout (Appendix D) that further explains the Roadside Inspection Program. If the driver
agrees to participate in the inspection process, the vehicle is inspected. If the driver refuses, the
vehicle is released and another vehicle is quickly directed into the test lane. The license plate
numbers of vehicles whose operators decline to participate in the Roadside Inspection Program
are recorded and entered into a laptop computer for later analysis.
A similar process exists if the team is using the stratified sample method. However, once the
vehicle enters the test lane and stops at the appropriate location, the BAR greeter determines the
vehicle model-year. Using a worksheet providing model-year stratification, the greeter
6
determines the model-year of the vehicle. If the vehicle is one of the desired models, the driver
is asked to participate in the Roadside Inspection Program. If it is not, the driver is thanked for
their time and the vehicle is directed out of the lane. Note that every driver has the option not to
participate. All testable vehicles receive a 90-second ASM 5015 and a 60-second ASM 2525
