The dieselgate scandal has really riled up the authorities. Germany’s motor vehicle regulator, the Federal Motor Transport Authority (KBA) will reportedly be running tests on more than 50 models that come from 23 German and foreign brands. The regulator suspects that there has been further manipulation of nitrogen oxide emissions from diesel engines, Reuters reports.

According to KBA, Volkswagen’s admission that it had doctored emissions test was one of the reasons that set off the investigations. Another reason, the regulator mentioned, was due to “verified indications from third parties regarding unusual pollutants emissions.”

Apparently, probes have begun more than a month ago. “Since the end of September KBA has been investigating whether further manipulation of emissions, of nitrogen oxides in particular, is taking place in the market,” the regulator revealed in a statement.


It compared emission results in a laboratory setting with readings that were taken from portable meters used in real-life tests. The regulators says that approximately two-thirds of the measurements have already been carried out ever since.

The statement also notes that, “partially increased nitrogen oxide levels in different driving and environmental conditions have been identified so far,” according to raw data collected. The KBA further mentioned in the statement, that it is currently in discussions with the manufacturers concerned.

Elsewhere, the United States Environmental Protection Agency (EPA) recently announced that it is set to expand its on-the-road emissions tests across all 2015 and 2016 diesel models that come from automotive brands in the States. The EPA has employed a new secretive methodology of conducting tests, to highlight discrepancies of emissions results against those put forth by manufacturers.
