How could some engineers cheat the entire VW corporation?<p>Germans are known for their ridiculously meticulous standards and testing. VW should have many in-house and external-independent labs performing tests.<p>The engineers who write the ECU code have a great distance from the mechanics who test every engine and car batch from their production line.<p>How did they never tested and engine entirely; power, emissions, consumption?<p>You may fool the regulators but you can&#x27;t fool your own mechanics.
