BMW is recalling 24,340 vehicles equipped with diesel engines from the 2009-11 model years that may fail to meet U.S. and California emission control requirements.
About 2,740 2011 and 2012 model year X5 xDrive 50i and X6 xDrive 50i vehicles, and 21,600 3-series diesel models, will be recalled, the automaker said. The recalls were scheduled for May 9, with a customer letter to follow, BMW North America spokesman Dirk Arnold said.
The vehicles were manufactured at factories in Spartanburg, S.C., and Germany.
BMW said certain emissions components, including the SCR catalyst, the DEF mixer and the EGR valve, may improperly overstate vehicle mileage, causing emissions standards to be exceeded and the illumination of the "Service Engine Soon" light.
BMW said the repair will require the inspection and replacement of one or more of the emissions components and the reprogramming of the vehicle's engine control unit.
