A former federal official and the Environmental Protection Agency said that German supplier Bosch didn't supply Volkswagen — or other automakers — with cheating software, implying that Volkswagen engineers acted alone in deceiving emission tests, Reuters reported (via Automotive News).
According to the report, Bosch supplies the engine control management unit for most four-cylinder diesel passenger cars, including Mercedes-Benz, BMW and others. Both BMW and Mercedes have said their cars do not have software that cheats emission tests.
According to the report, the U.S. House Energy and Commerce Subcommittee on Oversight and Investigations will consider recommending changes to the way regulators test emissions to more closely match real-world conditions.
Bosch said Tuesday that it supplied the units to automakers but "how these components are calibrated and integrated into complete vehicle systems is the responsibility of each automaker," Reuters reported.
Last month, a report said that Bosch warned Volkswagen of its illegal software in 2007. The supplier didn't comment on the report, citing contractual privacy with the automaker.
A former EPA official told Reuters that software to detect EPA test cycles would require significant effort by an automaker.
"It is highly unlikely that this additional software is in any computer that does not have a defeat device, as the code requires significant additional resources to write and it would be of no use unless a defeat device was being used," John German, a former EPA official and a senior fellow at the International Council on Clean Transportation, told Reuters.
