Official summary
A Delivery Stop has been issued on certain 2014 model year E89 vehicles produced from March to June 2013. The fuel pump pressure regulator could cause a noise that is audible to the driver. The fuel pump still functions properly in this case. Affected vehicles in center inventory must not be delivered until the in-tank fuel delivery unit has been replaced. Do not order parts at this time.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
