They have admitted that the software detects tests.

  Was the software designed only to detect tests? Or is detecting tests (and other cases where limiting performance has no adverse consequences) a side-effect of the system's intended behavior. For instance, suppose the vehicle was programmed to shut off its engine when stopped at a stoplight. Suppose the test scenario measures emissions while stopped at a stoplight...

    All of the reports indicate that the ECUs were programmed to detect tests and enable the changes that reduce NOx emissions. The intended behaviour was to have one performance profile for emissions tests, and one for power/efficiency elsewhere. The engine shutoff feature is irrelevant, as it happens in the wild when not running emissions tests.
