VW 2.0 TDI engine loses 15hp and 32lb/ft on emissions test mode.
 

TFLCar tested a Jetta on a 4WD/2WD dyno.
Peak hp didn't change much, while peak torque dropped.
Max drop was 15hp and 32lb/ft in the low range

Didn't watch the video since at work but what did they set as the benchmark? Did they test it on the dyno before the recall?

edit*
Ahh just found the article on Jalopnik too. VW set a mode that if only the drive wheels are in motion it detects that its getting tested activating cheats for emissions whereas if all 4 wheels are spinning it detects that its actually on the road NOT being tested. For your non-video people:

Is that why we get shafted with no awd diesel
