The Sole Engineer Charged In the Dieselgate Scandal Has Been Granted A Delay In His Sentencing

Judge Delays Sentence Of VW Engineer Assisting Courts In Dieselgate

The sole engineer charged in the Dieselgate scandal has been granted a reprieve of sorts by the courts as the judge has delayed his sentencing by three months.

The sole engineer charged in the Dieselgate scandal received reprieve of sorts from the courts as the judge sitting on the case delayed his sentencing for three months. James R. Liang, a German citizen who lives in Newbury Park, Calif., pleaded guilty last September to charges of conspiracy to commit wire fraud and U.S. clean air law violations.

Liang, a 34-year Volkswagen employee, helped to develop the diesel engine at the heart of the emissions rigging scandal. The Justice Department brought the charges in September.

Original Sentencing Date

Liang’s original sentencing was set for Feb. 1. However, U.S. District Court Judge Sean Cox delayed the sentence Tuesday to May 3 “to allow more time for defendant’s cooperation in the investigation.” In his court finding, Judge Cox said that Liang is cooperating in “the investigation and the potential prosecution of others.”

The veteran VW engineer worked in engine development in Germany in 2006. He was on the team that developed the EA189 turbodiesel engine for Volkswagen’s TDI series of Golfs, Jettas and Passats. According to the indictment, Liang was one of the engineers who developed the “defeat device” that enabled the inherently dirty engine to pass emissions testing.


The Wolfsburg engineers realized in 2006 that the powerplant wouldn't meet the twin goals of air quality and consumer popularity. The engine apparently could be optimized for one or the other but not both. As a result, the engineering team installed the “defeat device” that allowed the powerplant to appear clean, while it was emitting up to 40 times the allowable limits of nitrous oxide (NOx), a primary diesel pollutant.

No Comment All Around

According to Reuters, Liang’s attorneys did not comment. The Justice Department and Volkswagen also declined to comment.
