Fiat Chrysler, Italy face EU questions over diesel emissions on the Fiat 500x
The European Commission called on Italy to provide proof against Germany's allegation that Fiat Chrysler used illegal exhaust emissions defeat devices, stepping up pressure on the group amid accusations of emissions manipulation against it in the U.S.
Germany has asked the EU executive to mediate its dispute with Italy, which rejected Germany's allegations of hidden software on the Fiat 500X, Fiat Doblo and Jeep Renegade models that allowed excess diesel emissions.
Germany's motor vehicle authority, the KBA, began testing the vehicles of several manufacturers, including Fiat Chrysler, after Volkswagen Group's admission in September 2015 that it cheated emissions tests.
An EU source said that testing carried out on one Fiat 500X vehicle at the EU's own vehicle testing laboratory north of Milan showed suspicious emissions behaviour.
Fiat Chrysler declined to comment.
