Service bulletin B630321

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

B6307192019-12-16. Service bulletin. DELIVERY STOP: PROGRAMMING CONTROL MODULES (TAIL LAMPS). BMW of North America LLC has issued a Delivery Stop (effective October 24 2019) on a small number of Model Year 2020 BMW X6 vehicles that were produced in the date range shown above. In extremely rare instances dimming of the tail lamps in the "Welcome mode" and "Goodbye mode" could cause the left or rear tail lamps and/or brake lamps to not illuminate. It is unlikely that the left and right tail lamps will not illuminate simultaneously.
