Gov't Expands Investigation Of VW Diesel Cars

WASHINGTON (AP) - The government is expanding its safety investigation into possible engine problems in 100,000 Volkswagen diesel cars.

The National Highway Traffic Safety Administration says it has received 160 complaints and field reports about engines stalling or losing power. The reports involve 2009 and 2010 model year Jettas and 2010 models of the Golf and the Audi A3 with TDI clean diesel engines.

The safety agency says one minor crash has been reported related to a failure of the car's high pressure fuel pump. About half of the reports describe engines stalling, with many of them occurring at highway speeds in traffic.

Volkswagen told the government that the problem could be related to gasoline contamination from drivers pumping the wrong fuel. The investigation began in August.
