The company previously claimed its Euro6-compliant EA288 engines do not implement any software tricks to cheat emissions tests, however the inquiry initially left open the possibility that such software may have been used for earlier Euro5-optimized variants.
The company has now cleared all Euro5 and Euro6 variants, noting that “no software constituting an improper defeat device as defined in law is installed in vehicles with EA288 engines.”
It is unclear if the automaker is investigating possible use of similar software in other engine types, though the scandal currently appears to be focused solely on the EA189 mills that sparked the fiasco when the Environmental Protection Agency last month went public with its accusations of non-compliance.
Engineers may have adapted the cheat software to work with several different engine variants and individual models, affecting nearly 11 million vehicles sold across the globe. US-market vehicles are expected to receive a urea-injection system or upgraded catalytic converter, while other markets could receive just a software update to bring emissions down to levels compliant with local regulations.
