IMHO, the real risk is not just the fines from EPA and its overseas counterparts, but potential lawsuits from customers if the cars become unregisterable or unreliable.
If I read this correctly, the cheating code is manipulating EGR valve because the hot sooted pre-particulate trap exhaust gas being fed to the intake can really clog up the intake valves, where temperature is lower. That means if the "test mode" is constantly on, the engine would become severely unreliable. Losing a few horsepower or a few mpg is a relatively minor problem, but requiring intake valve cleaning every 20-30k miles would be a huge problem.
