Who is 'they' ?  The factory builders of industrial VW engines I suppose.
Usually stationary engines are not too subject to emissions laws I don't
think ..at least not older ones.

fwiw, I have read recently  that an electronically controlled TDI will get
better fuel mileage with the EGR system working. ( and it's  common to
remove that, plus the stock cat sometimes. , for those conversions in
vanagons )

80's era diesel engines are generally, very, very polluting.  Like what
comes out the tailpipe is a deadly poison.
Each driver gets better fuel mileage for themselves at the cost of everyone
else's and the planet's health.

very short term gain. And don't breathe it !  - what comes out the tail
pipe.
