A former Volkswagen executive has pleaded guilty to two charges related to the company’s diesel emissions scandal. He is the second VW Group employee to do so, following retired engineer James Liang pleading guilty last summer.

The VW Group executive, Oliver Schmidt, was based outside of Detroit and was in charge of emissions compliance for Volkswagen in the years before the company was caught using illegal software to cheat on federal emissions tests. Schmidt, a German citizen who was 48 when he was arrested in Miami in January on vacation , was originally charged with 11 felony counts. In accepting a plea deal from US federal officials , Schmidt will only plead guilty to two charges: conspiracy to defraud the US government and violate the Clean Air Act, and making a false statement under the Clean Air Act.

Schmidt will be sentenced in December. He could face up to seven years in prison, as well as fines from $40,000 to $400,000, according to the plea agreement. After that, Schmidt could also be required to serve four years of supervised release.

“In the summer of 2015, Schmidt participated in discussions with other VW employees about how they could answer questions posed by US regulators about the NO x [nitrogen oxide] emissions of the Subject Vehicles, without revealing the defeat device,” the plea agreement says. The document goes on to describe conversations Schmidt had with government employees in which he did not bring up the illegal software and paperwork submitted by VW Group that did not disclose the software, although it legally had to.

Schmidt is one of six executives that the US Department of Justice indicted in January, and he’s the only one of the six who’s been arrested. The other five are presumed to be in Germany still. The DOJ has also announced charges against a manager at Audi, which is part of VW Group and whose diesel cars were among the first to receive the illegal software.
