It has been roughly seven years since Volkswagen was caught cheating during emissions testing, now referred to as the infamous Dieselgate incident.

The scandal cost Volkswagen $40 billion, and quite a few manufacturers were caught up in the aftermath. Since then, it has been a never-ending streak of lawsuits against Mercedes-Benz, Porsche, and Audi.

Dieselgate is set to make a serious comeback in the coming months. This time it's Suzuki and Stellantis facing the wrath of the European Union's agency for criminal justice cooperation.

Both manufacturers allegedly used the same defeat device tactic the Volkswagen Group infamously used in various models, including the Jetta, Touareg, Porsche Cayenne, and Audi Q7.

Both Suzuki and Stellantis' offices were raided this week in a case put together by German, Hungarian and Italian authorities. Automotive News Europe reports that Suzuki is suspected of fraud for selling more than 22,000 models with a defeat device installed. The models affected include the SX4 S-Cross, Swift, and Vitara.

The scandal also includes Stellantis (formerly FCA), who agreed to sell diesel engines made in Hungary to Suzuki in 2011. The two companies first allied to build engines in Asia in 2005.

From 2011 onwards, Suzuki purchased engines directly from Fiat in Hungary, then fitted them into cars produced at its Hungarian factory.

The third party in this alleged crime is Marelli, who provides software to Stellantis. The business premises of all three companies were searched in Germany, Italy, and Hungary earlier this week. According to the report, prosecutors seized communication data, software, and planning documents.

"The devices were allegedly fitted in the Italian-built diesel engines of large numbers of cars, giving the impression that the vehicles' nitrogen oxide emissions were in line with EU regulations," the agency said.

A spokesperson from Suzuki confirmed that the company and its local management in Germany are cooperating with the investigation and authorities.

Stellantis said that FCA Italy has been asked to provide information and documents related to the matter and intends to cooperate fully.

Marelli is also cooperating with investigators. "Marelli is confident that we have always conducted our operations in full compliance with regulations," it said.

If found guilty, the repercussions could be huge. While Suzukis aren't sold in the USA, the manufacturer is partnered with other huge companies like Toyota. The two companies are reportedly working to produce a new small crossover to take on the Kia Seltos and Nissan Kicks.
