Wow. German Engineering used to be among the greatest in the world... now they’re resorting to cheating on tests? Sad.
They were cheating on a test nobody could pass.
If you work on any modern German cars you will understand that is no longer the case. Beautifully over engineered, many with fatal flaws that will set you back 10s of thousands of dollars or make the car too expensive to repair. I own a fleet of German cars and perform the repairs.
