Volkswagen to put special fuel caps on diesels

DETROIT Volkswagen (VLKPY) is replacing the fuel tank covers on more than 200,000 of its diesel vehicles sold in the U.S. and Canada to remind owners to fill their tanks with diesel not gasoline.

The company said Tuesday it's taking action after getting a small number of reports of drivers filling diesel tanks with gas. Using the wrong fuel can damage the engine.

Volkswagen will alert affected customers. Dealers will put on a new fuel cap with yellow "Diesel'' lettering for free.

The company says the service action involves 209,415 vehicles, including the Jetta and Jetta SportWagen from the 2009-'12 model years and the Golf TDI from the 2010-'12 model years. Around 9,000 Audis also are affected.

Volkswagens from the 2013 model year have the new gas caps and aren't affected.
