## NHTSA's summary

"SI B12 01 14 February 2016 Electrical Systems Technical Service This Service Information bulletin supersedes SI B12 01 14 dated April 2014. Due to an error in the DME \(Digital Motor Electronics\) software, the required oxygen sensor onboard diagnostics \(OBD\) is not functioning. As a result, the ""Readiness bit"" confirming a successful completion of the oxygen sensor diagnostics will not be set. In order to remedy the situation, BMW is conducting a Voluntary Emissions Recall Campaign to reprogram the control units \(DME\) on all affected vehicles."
