Alizium Auto Blogs: BMW finally acknowledges turbo lag, will update software

Filed under: Maintenance, BMW

Countless BMW owners have been frustrated for some time with software-induced turbo lag on their N54 3.0-liter twin-turbo inline-6 engines. While early models were acclaimed for their immediate power delivery, it seems BMW felt it necessary to address "specific noise concerns" with the engine and made software changes in models built between June 2006 and March 2008. Those changes introduced turbo lag - the noticeable delay between the throttle and the time it takes for the turbocharger to spin and produce power. Enthusiasts were up in arms, but BMW refused to recognize their concerns (addressed on nearly every BMW message board, and by the BMW Car Club of America)... until now. According to a statement from the automaker, new software will be released in January 2009 that will restore the original turbocharger response. Of course, it comes with a warning that it may result in "slightly increased engine noise levels." As if an enthusiast cares... Thanks for the tip Michael!
