The Defeat Device
Volkswagen equipped about 500,000 US diesel vehicles — 2.0-liter TDI Jettas, Passats, Golfs, Beetles and the Audi A3, model years 2009–2015 — with “defeat device” software. The software detected when a car was being emissions-tested and switched on full pollution controls, then dialed them back during normal driving so the cars delivered better performance and mileage while emitting nitrogen oxides at up to 40 times the legal limit. VW had marketed the cars as “clean diesel.”
It was deliberate, coded deception — which is what made “dieselgate” a landmark of corporate fraud, not just an emissions failure.
The Settlement
In 2016, Volkswagen agreed to spend up to $14.7 billion to resolve US claims from the EPA, California regulators and the FTC. About $10 billion went to consumers — buybacks, lease terminations or approved fixes plus cash restitution for owners and lessees — and roughly $4.7 billion funded environmental mitigation and clean-vehicle investment. VW also faced additional criminal and civil penalties beyond this consumer settlement, pushing its total costs far higher worldwide.
The consumer buyback was unusually generous because the cars could not be made both compliant and as advertised.
What It Changed
Dieselgate reshaped emissions enforcement and accelerated the industry’s pivot away from diesel toward electric vehicles. For consumers, the lasting lesson is that “clean” performance claims can be tested and enforced, and that a defeat device is treated as fraud. The US consumer program has concluded; related litigation continued in other countries.
