Is this also likely to affect Skoda as well? They are not present in the USA but what about all other regions? Interesting if Skoda chose to or not to 'install' or 'activate' the (default?) defeat device code.
Skoda UK is definitely affected else they would not repost the VW statement on the Skoda UK website:

Fact Sheet: Light-duty diesel in-use tests
In 2013, the ICCT contracted with the Center for Alternative Fuels, Engines and Emissions at West Virginia University to conduct in-use emissions tests on three light-duty diesel vehicles: a Volkswagen Jetta, a VW Passat, and a BMW X5. The full results and analysis are available here.
Key information
•The testing was done using a portable emissions measurement system (PEMS), which provides a continuous stream of vehicle data signals including emission rates, velocity, acceleration, road gradient and exhaust temperature. PEMS data was gathered over a variety of pre-defined test routes exhibiting diverse driving conditions pertinent to major United States population centers located in California. The city-driving route selected was the “Los Angeles Route Four” loop (LA4), which was ultimately used in developing the original FTP vehicle certification cycle [11], with some minor modifications at locations where the traffic pattern or roads have changed since the FTP’s development.
•Additionally, the Passat was operated over an extended distance of nearly 2,500 miles predominantly composed of highway driving conditions between California and Washington State.
•The three test vehicles were certified to US-EPA Tier2-Bin5 and California LEV-II ULEV emissions limits and were equipped with NOx after-treatment technologies: the Jetta was tested with a lean-NOx trap (LNT), the Passat with a urea-based selective catalytic reduction (SCR) system, and the BMW X5 with an SCR system. All three test vehicles were thoroughly checked for possible engine or after-treatment malfunction codes using an on-board diagnostics (OBD) scanning tool, with none of them showing any fault code or other anomalies. No reduction in catalytic activity due to aging was expected, as the total mileage was relatively low (< 15,000 miles) for all test vehicles.
•The two VW vehicles were tested over the FTP-75 certification cycle at California Air Resources Board’s (CARB) El Monte vehicle certification test facility, and their NOx emissions were below the US-EPA Tier2-Bin5 standard.
•
Real-world NOx emissions, as reported by the PEMS, were found to exceed the US-EPA Tier2-Bin5 (at full useful life) standard by a factor of 15 to 35 for the Jetta, and by a factor of 5 to 20 for the Passat, over five pre-defined routes categorized based on their predominant driving conditions (highway, urban/suburban, and rural-up/downhill). The BMW was generally at or below the standard and only exceeded the standard during rural uphill operating conditions.
•The VW vehicles met the emission standard on FTP-chassis dynamometer tests, which include cold-start NOx emissions. But the on-road emissions testing was performed with the engine and after-treatment in warmed-up condition (i.e. warm/hot start), and the VW vehicle emissions were 5 to 35 times the standards during on-road testing, which did not include cold-start NOx emissions. This inconsistency was a major factor in ICCT's decision to contact CARB and EPA about our test results.
•In general, carbon monoxide (CO) and total hydrocarbon (THC) emissions were observed to be well below the U.S. regulatory levels for all three test vehicles. Particulate number (PN) emissions, inferred from particle sensor (PPS) measurements, were observed below the Euro 5b/b+ standard except during vehicle operation exhibiting DPF regeneration events.
•This project was part of a larger meta-analysis of PEMS data from EU (Euro 6) and US (Tier 2 Bin 5/ULEV II) diesel passenger cars. (For details on this project, see
http://www.theicct.org/real-world-ex...rn-diesel-cars) This broader study analyzed the on-road emissions performance of fifteen new diesel passenger cars, twelve certified to the Euro 6 standard and three to the US Tier 2 Bin 5 standard (which is more stringent than Euro 6). Emissions were measured over 97 trips, totaling more than 140 hours of operation and 6,400 kilometers driven. On average, real-world NOx emissions from the tested vehicles were about seven times higher than the limits set by the Euro 6 standard. In most cases the exceedances found could not be attributed to “extreme” or “untypical” driving. Instead, they were due to transient increases in engine load typical of everyday driving (e.g., going up a slight incline), or to normal regeneration events in the diesel exhaust aftertreatment systems.
•Performance differences among the vehicles tested indicate that the technologies for real-world clean diesels already exist. Some of the tested vehicles, such as the BMW X5, had average emissions below Euro 6 emission limits, suggesting that the technologies to achieve that level of performance are available.
