BMW recalling 24,000 vehicles over emissions problem

BMW wants to take another look at over 24,000 vehicles it's sold in the United States. No, this isn't just to check out how they're holding up in the real world, it's to make sure the smoke coming out of the tailpipe is clean enough.

BMW is recalling a total of 24,340 vehicles from the 2009-2011 model years – roughly 2,740 2011 or 2012 X5 xDrive50i and X6 xDrive50i vehicles as well as 21,600 335d models – because some parts of the emissions system (the DEF mixer, EGR valve and SCR catalyst) can incorrectly calculate the vehicle mileage. This can cause too many emissions to come out of the tailpipe, according to the California emission control rules. The recall will start May 9. Drivers should be on the lookout for letters after that date, a spokesman told Automotive News.

Just two months ago, BMW had to recall 1.3 million 5 Series and 6 Series vehicles from the 2003 to 2010 model years, 368,000 of them in the U.S.
