DETROIT (AP) — Volkswagen’s plan to fix most of its 2-liter diesel engines that cheat on emissions tests includes a computer software update, two dealers who were briefed on the matter by executives say, and also a larger catalytic converter to trap harmful nitrogen oxide.
The dealers said Friday that limited details of the plan were revealed last week by Volkswagen of America Chief Operating Officer Mark McNabb.
One dealer said the group was told that early testing of a small sample of repaired cars showed that the fix made “no discernable difference” in the cars’ mileage, horsepower or torque. Both dealers say they were told that more testing was needed and that the plans still had to be approved by the U.S. Environmental Protection Agency and the California Air Resources Board.
