In North America it's mostly a non issue, pretty much every car sold
since 1996 in North America is OBDII with the standard connector.

Elsewhere is a different story, as the article you mentioned indicates.
It says that all diesel vehicles after 2004 in the EU must be OBDII, yet
the 2006 Skoda Fabia diesel I rented last month in Austria certainly
didn't have the OBDII connector (it had a connector, but looked
different). Does anyone know if perhaps in the EU OBDII is required now,
but the connector is still non standard? Or is it just the EU connector
standard is different from North America?

Thanks, TTYL
