Service bulletin 121512

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.

NHTSA's summary

"MSA II: Automatic Start/Stop System Benefits and Operation. Some drivers have expressed the desire to deactivate this function in certain situations. This can be done manually via the Automatic Start/Stop function button with the LED switched on, indicating that the start/stop function is deactivated. However, by default, the Automatic Start/Stop function is reactivated each time the engine is started. At the request of an owner, it is possible to modify this default logic to ""Last user mode."" With this logic, the current MSA's activated or deactivated setting is stored and used on the next trip. Note: All new BMW M models have the ""Last user mode"" as the default setting from production."
