I know it doesn't help you with your problem, but how about explaining to this ugly american what euro 0/1/2 are.

A net search for Euro 0/1/2 finds:

European Union emission regulations for new light duty vehicles (cars and light commercial vehicles) are specified in the Directive 70/220/EEC. This basis Directive was amended a number of times, some of the most important amendments including:

a.. Euro 1 standards (also known as EC 93): Directives 91/441/EEC (passenger cars only) or 93/59/EEC (passenger cars and light trucks) b.. Euro 2 standards (EC 96): Directives 94/12/EC or 96/69/EC c.. Euro 3/4 standards (2000/2005): Directive 98/69/EC, further amendments in 2002/80/EC d.. Euro 5 standards (2008): Proposed regulation [COM(2005) 683] published in December 2005 Fuels. The 2000/2005 standards were accompanied by an introduction of more stringent fuel regulations that require minimum diesel cetane number of 51 (year 2000), maximum diesel sulfur content of 350 ppm in 2000 and 50 ppm in

2005, and maximum petrol (gasoline) sulfur content of 150 ppm in 2000 and 50 ppm in 2005. "Sulfur-free" diesel and gasoline fuels (? 10 ppm S) must be available from 2005, and become mandatory from 2009.

Emission Testing. Emissions are tested over the ECE 15 + EUDC / NEDC chassis dynamometer procedure. Effective year 2000 (Euro 3), that test procedure was modified to eliminate the 40 s engine warm-up period before the beginning of emission sampling. This modified cold start test is referred to as the New European Driving Cycle (NEDC) or as the MVEG-B test. All emissions are expressed in g/km.

For PM measurements, particle number limits have been considered at the Euro

5 level, in addition to the existing mass-based limits (NEDC). The draft Euro 5 proposal indicates that number-based PM limits should be implemented once the measurement methods are established, following the completion of the UN/ECE Particulate Measurement Programme (PMP). At the time of the publication of the Euro 5 proposal, its mass-based PM emission limits could only be met by closed particulate filters. Number-based PM limits would prevent the possibility that in the future open filters are developed that meet the PM mass limit but enable a high number of ultra fine particles to pass.

Once the PMP work is completed, changes may be also introduced to the PM mass measurement procedure, which may require adjusting the proposed Euro 5 PM mass emission limit.
