The Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) have approved Volkswagen's modifications to its 3.0-liter diesel engines, which had been rigged to pass pollution tests, Bloomberg reported.
Rather than having to offer to buy back affected vehicles, VW will be able to fix the problem with sofware and hardware upgrades.
According to Reuters, VW agreed to spend at least $1.22 billion to fix or buy back nearly 80,000 vehicles as part of a May settlement. The auto group also agreed to pay vehicle owners who recieved fixes between $8,500 and $17,000.
The updates will affect luxury 2013-2016 model-year diesel Porsche Cayenne, Volkswagen Touareg and 2013-2015 Audi Q7 SUVs.
In 2015, VW admitted that it rigged about 11 million diesel vehicles across the globe to cheat emissions tests. In April of this year, VW plead guilty to three felony counts in the U.S. and was sentenced to three year's probation.
