BMW, in an official statement, acknowledged the turbocharger lag for the 335i/xi and 535i/xi models and have addressed the issue with updated turbocharger software that is available upon request. The statement further states that the X6, 135i, and 3 Series/5 Series vehicles manufactured from March 2008 onwards are not affected with the lag.

The latter part of the statement tells owners how to avail of the update: “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.”

It’s good to see BMW finally own up to these turbo lag issues that have been brought up by owners and publications. This optional update gives affected owners a choice between having the lag and risking higher engine noise levels.

Last week, BMW made an announcement that they will be shipping out the facelifted BMW 3-Series. The bumper, hood and fascia have been tweaked but I still don’t find it attractive enough. No new offerings aside from the facelift but the US market will finally get the 335d equipped with 3.0L twin-turbo, 265-hp, inline-six diesel.

Anyway, the cars will be debuted in Paris though. If we’ll get any more drum banging for these cars until then, we’ll know soon.
