10 Years On, Volkswagen Is Still Feeling The Legal Heat Of Dieselgate

Nearly ten years after the Volkswagen “Dieselgate” emissions cheating scandal first stunned the automotive world, a German court has convicted four former VW managers for their involvement in the widespread fraud. The convictions in Braunschweig mark another chapter in the ongoing legal fallout from the manipulation of millions of diesel vehicles designed to deceive regulators and consumers.

Founded: 28 May 1937
Founder: German Labour Front
Headquarters: Wolfsburg, Germany
Owned By: Volkswagen Group
Current CEO: Thomas Schaefer

The verdicts, delivered on Tuesday, May 27, 2025, after a four-year trial, saw significant prison time handed to some of the accused. Jens Hadler, who led diesel-engine development at VW from 2007 to 2011, received a sentence of four and a half years. Hanno Jelden, a former top engineer and head of drive electronics, was sentenced to two years and seven months for aggravated fraud linked to the sale of nearly three million affected cars. All convicted individuals had initially sought acquittals.

Details Of The Deception And Judgment

The court found the managers culpable in a scheme that equipped vehicles with so-called defeat devices. This software allowed cars to meet emissions standards during laboratory testing, but emit significantly higher levels of toxic nitrogen oxides during real-world driving. Judge Christian Schütz stated that certifying authorities “weren’t told that the emissions were much higher in real drive,” adding, “It’s crystal clear that this wasn’t in line with the law.”

Two other former Volkswagen employees received suspended sentences. Heinz-Jakob Neusser, a former head of engine development, was given a suspended sentence of one year and three months. The judge noted evidence suggested Neusser learned of the rigging in 2013, but still caused nearly $30.7 million in damages by not intervening. A fourth, lower-ranking manager identified as Thorsten D., received a suspended sentence of one year and ten months, reportedly due to his early cooperation with U.S. authorities. The judge acknowledged that sentences were reduced for all due to the extended duration of the prosecution. Judge Schütz also emphasized that while many others at VW participated, the convicted individuals held leading roles and “committed crimes for many years.”

The Lingering Impact Of Dieselgate

The Dieselgate scandal, which erupted in September 2015 when the U.S. Environmental Protection Agency exposed the cheating, has had profound and lasting consequences. Volkswagen itself has incurred costs exceeding $33 billion in fines, compensation to owners, and legal settlements worldwide. The company settled a criminal probe with German prosecutors in 2018 by paying a €1 billion fine. The scandal also led to the departure of then-CEO Martin Winterkorn, whose own trial related to the matter has been repeatedly delayed due to health issues.

While these convictions mark the Braunschweig court’s first verdicts against senior staff from VW’s main brand, the legal saga is far from concluded. 31 other individuals remain indicted in Braunschweig, with the next case scheduled to begin in November. In the United States, two VW managers served prison time, and former Audi head Rupert Stadler received a suspended sentence and a substantial fine in Germany, though that verdict is pending appeal. Both Neusser and Hadler also face charges in the U.S. but are protected from extradition as German citizens.

Broader Industry Ramifications

The fallout from Volkswagen’s deception extended beyond the company itself, prompting intensified scrutiny of diesel emissions across the automotive industry. Companies like Bosch, which supplied software components, faced hundreds of millions in fines. Other automakers, including Fiat Chrysler (now Stellantis), also paid hefty fines for their own diesel emissions irregularities. Nearly a decade on, the Dieselgate convictions serve as a continuing reminder of one of the largest corporate scandals in automotive history and the persistent efforts to hold individuals accountable.
