My question is HOW did the car *know* it was being *tested* for emissions?

What I don't understand is that VW had to submit test results from a
(supposedly) independent company in Europe to get certified in Europe
for the 11 million cars that might be affected.

They apparently contracted that job out to Applus Idiada of Spain.

Has anyone any idea how Applus Idiada verified the wrong numbers?

One likely way would be that they also did it via a dyno test.
It's certainly easier and more practical, consistent, than driving
on roads.
