Chibong,

The German exhaust emission regulations are very different
from the US standard. They are not comparable. But on the
other hand, the parts are identical, except one major part:
The Engine Management Box

I have no details on the emission test specifications, but
to get an approval for an engine / car model combination
you have to pass a test with a duration of about three
days. For a renewal of the certificate (every two years)
it does not need more than a CO reading according to the
manufacturer definition.

It does not help you if some Germans will send you their
computer print of local exhaust emission test. It just
tells about some CO readings, idle speed, oil temps and
other for you uninteresting details.
