BMW broadens engine bolt recall to nearly half-million cars worldwide

Almost one month ago, we reported on a BMW investigation into a potentially defective bolt that lived in the company's VANOS variable valve timing system. At that point, the potential recall was seemingly limited to Chinese-market cars; the company was filing a recall application with Chinese officials.



Today, Bloomberg is reporting that the engine bolt issue has expanded into a recall for several world markets, involving some 489,000 vehicles. BMW was able to verify that report to Autoblog, while also providing a great deal more detail about the issue and vehicles affected.



The recall affects vehicles powered by N55 inline six-cylinder gasoline engines equipped with VANOS and Valvetronic technologies. 1 Series, 3 Series, 5 Series and 5 Series Gran Turismo, X3, X5, X6 and Z4 models from the 2010 to 2012 model years are included, as is the 2012 6 Series.



In total, 156,137 vehicles in the US are affected by the recall, which BMW says was filed with the National Highway Traffic Safety Administration late on Wednesday.



In rare cases, the bolts holding the VANOS unit housing may become loose, or, in "extreme" cases, break. A broken bolt may trigger an engine warning light or send the engine into safe mode if the VANOS unit is compromised. Ignoring the issue could cause "no start conditions," stalling and further engine damage.



As you might suspect, BMW recommends that owners observing engine warning lights should arrange for service.



NHTSA has yet to issue its own recall notice, though presumably they are forthcoming, and BMW's own statement can be seen below.
