WASHINGTON — Leaders of a House committee are requesting more details and documents from Volkswagen after federal regulators said the carmaker cheated a second time on emissions tests.

The Environmental Protection Agency said this week that VW programmed about 10,000 cars with larger diesel engines to emit fewer pollutants during tests than in real-world driving.

The charges follow VW’s admission in September that it rigged emissions tests for four-cylinder diesel engines on 11 million cars worldwide, including almost 500,000 in the United States.

Leaders of the House Energy and Commerce Committee sent a letter Tuesday to Volkswagen’s U.S. CEO, Michael Horn, requesting additional information about so-called defeat devices designed to skirt emissions controls.

The bipartisan letter set a Nov. 16 deadline for Horn to respond.
