Additional tests carried out on Fiat Chrysler models during Italy‘s main emission-cheating investigation have found no illegal engine software, Italy’s transport minister said on Wednesday.

A final report on the new tests is due to be published within days, a ministry official said.

Transport Minister Graziano Delrio told a parliamentary hearing that Rome had sent a separate report to German authorities refuting their allegations and showing that three FCA models — Fiat 500X, Jeep Renegade, and Fiat Doblo — were compliant with regulations.

Delrio said the European Commission, which is mediating in the dispute, was supportive of Italy’s position.
