While turbo charging a diesel increases efficiency and reduces CO, HC, and
soot emissions, the process drastically increases the production of NOx.
This is one of the pollutants that make turbo diesel technology to be become
so regulated. EGR, Catalysts, and Urea injection are being used to control
it.

Emissions who needs emissions? I figure with being turbo it may burn cleaner
than my n/a? Do any of you think they used the tdi or industrial use?

ADE is the code for Industrial 1.9TD
ADG is for Industrial 1.9NA
AAZ is the most common code for automotive 1.9TD

All of the above were sold over a period of years with differences for
different markets, intended applications, parts evolution, so no two with
the same 3 letter code are necessarily exactly alike in every way.
Different turbos, pumps, manifolds, emissions fittings, etc, same code.
