[T3] 66 Squareback Now Mine

[Sean Bartnik]

I was reading about this issue as well and as I recall, yes, the system you identified was what EPA determined was a defeat device because it disabled the EGR system below certain temperatures (presumably to improve cold-engine driveability). 

As to why it's still there on your car, most likely the car was sold before EPA figured it out and either the owner "forgot" to bring it in for the fix or the dealer "forgot" to fix it along the way. 

Probably there was never an actual recall, most likely EPA fined VW and that was that.
