I figured this deserved a new thread, but for those of you who own an N54 car and are familiar with the dreaded turbo lag issue cropping up from the 29.2 and above software, you'll be delighted to hear the following...

Thanks to our friend Satch Carlson at Roundel who took my letter and others regarding the turbo lag, he was able to track down details on the problem and actually get BMW to admit the problem and announce a software updare.

BMW's official statement is below after Roundel threatened to run all of our letters (which I believe should STILL be run) -- thanks Satch!!

"In an effort to address specific noise concerns, BMW updated the turbocharged engine software on 335i/xi and 535i/xi models built from June 2006 through March 2008. The updated software causes a small amount of increased “turbocharger lag” under certain circumstances and, while not substantial, the lag may be perceptible to the most sensitive BMW drivers. X6, 135i, and 3 Series/5 Series vehicles from March 2008 production onward are not affected. Release of the new software to restore the original turbocharger response is planned for January 2009, and it will be available for vehicles produced from September 2007 through March 2008 when they are brought to an authorized BMW center for a repair which requires a programming update. Clients with vehicles produced from June 2006 through September 2007 may request installation of the January 2009 software update. Clients who get this update should understand that there is a possibility of slightly increased engine noise levels under certain circumstances."
