A federal judge has signed off on Volkswagen's settlement with regulators to resolve civil claims over diesel vehicles powered by its 3.0L V-6 TDI engine, the company has announced.

Judge Charles R. Breyer of the U.S. District Court for the Northern District of California granted final approval on May 17. The U.S. Environmental Protection Agency and California Air Resources Board have also approved the agreement.

In December, Volkswagen reached a settlement with the regulators on the 3.0L engines that would require the automaker to pay $225 million toward emissions reduction and $25 million to support the use of zero emission vehicles (ZEVs) in California. The engines were fitted to about 78,000 vehicles.

Vehicles covered by the 3.0L settlement include 2009 to 2016 model-year Touareg, 2009- to 2015-MY Audi Q7 and 2013- to 2016-MY Porsche Cayenne Diesel. Other models include 2014-MY, 2015-MY, and 2016-MY Audi models including the A6, A7, A8, A8L, and Q5.
