Volkswagen has bought back or repaired more than half of the 475,000 vehicles with 2.0-liter diesel engines that failed to meet emissions standards as part of a federal settlement about six months after it began the program.

The company provided the update to the U.S. judge overseeing the settlement in a letter sent April 14. The company provided a copy of the letter to Automotive Fleet.

Volkswagen has repurchased or terminated leases on nearly 238,000 vehicles and repaired 6,200 other vehicles. The company has admitted to installing cheat software that enabled the vehicles to pass emissions tests but emit more than 40 times the pollution allowed by the Clean Air Act in daily driving.

The company has agreed to buy back or repair 85% of the vehicles by 2019.
