Volkswagen emissions tricks do not seem to have affected the cars’ emission in Finland. It shows laboratory tests carried out by VTT Technical Research Centre. Cars with and without manipulated software were virtually the same test results.
In September 2015 revealed that Volkswagen had manipulated the results of emission tests for diesel cars and to their actual emissions are higher than the nitrogen oxide emissions emission tests show.
The software in the cars were programmed to give a specific ruling under test conditions and then return to another position when the car is running as usual.
The Volkswagen Group has announced that it will recall 64,000 cars in Finland to repair them. In total, the cheating 11 million cars.
But VTT tests show that engineered diesel engines get the same results in the test conditions such as Volkswagen engines without the engineered software.
VTT has tested eight Volkswagens with EA 189 engines which the manufacturer is equipped with cheating the program and five cars without the program.
The results are almost identical. The mean values are very close, and not even the extreme values are very different.
– The results are confusing, says VTT’s leading researcher Juhani Laurikko.
Trying to fool the software
According Laurikko it is possible to cheat the program has operated in cars that have been sold in the United States and which produced results that have helped the cars to keep within the strict emission limits.
The same program has not worked in Finland or so there have been some type of error in those very cars that VTT has tested that makes the end result is the same.
Juhani Laurikko says it will go ahead with the test and try to trick the engineered software to see if the final results are still the same.
EU limit values for nitrogen oxide undercut by all the cars in VTT’s test.
– This could mean that nothing will change in most of the cars to be recalled and repaired in Finland, says Juhani Laurikko at VTT.
The tests delayed
Transport Safety Agency follows the department Toni Palladino Puro emissions scandal. He says that according to the original schedule should Volkswagen recalls in Finland have already begun with updates of the Passat models with the 2.0 TDI engines.
The German authorities have not given permission to begin the repairs in Germany and it has made the recalls were also delayed in other countries.
In Finland, the newspaper Tekniikan Maailma ordered a thorough investigation of the Volkswagen Cars’ engine power and emissions before and after the removal of manipulated software.
The survey shall be conducted by VTT and made of EA 189 engines. The testing begins when the recalls were started in Finland.
