They are watched more closely and sometimes have video cameras. The actual testing is no different than normal. Plenty of people delete their EGR's here and get lucky finding a shop that doesn't car but as a rule it's a requirement. In 10+ years of Z ownership they have tested for EGR functionality every time. They don't seem to care if it's full operational though just so long as they can get the idle to drop even a small amount.
